Glitch

A Glitch (also known as a bug) is a fault in a runtime (program) that causes the game to function improperly. The severity of glitches can vary. One glitch caused a player's name to appear as "null" immediately after login; another hard-to-find, yet serious bug allowed players to kill other players outside of the Wilderness. Abuse of such glitches, such as during the World 111 Glitch (which allowed players to attack other players outside of the Wilderness), is a severe offence which is punishable by a permanent ban under Rule 4 of the Code of Conduct.

Jagex recommends that if a player finds a bug or glitch in RuneScape that they should report it to Jagex immediately, via the Submit a Bug Report screen on the RuneScape main site.

Famous Bugs/Glitches
'''Note: All glitches listed on this page have been fixed by Jagex. Please do not list any glitches that haven't been fixed yet.'''

World 111 Glitch
One infamous example of bug abuse was the World 111 Glitch - also called the World 111 Massacre or the Falador Massacre (after where the glitch occurred). On the day of 6 June 2006 (or 06/06/06, oddly enough) a player named "Cursed You" held a party at his house celebrating level 99 Construction, and eventually expelled all the guests. Those in the dungeon and fight arena were able to kill anyone, anywhere. The resulting PK rampage caused many deaths and the permanent banning of most participants. Although the owner of the house was not banned for the massacre, he was banned for real-world trading later on.

Moderators tried to tell people to bank their items and 'glory' teleport but they were barely seen amongst the mass amount of followers.

This bug remained on RuneScape for about an hour and was fixed immediately after it became known to Jagex. The repercussions of this glitch are still being felt today, as some of those banned and/or killed owned rare items such as party hats. The removal of the players meant the rare items were deleted also.

Party hat duplication glitch
The glitch was not an attempt to duplicate items. A player named SixFeetUnder had been experimenting with RuneScape by using a third-party program called Auto-rune in an attempt to simply trade the scythe. Although the player never managed to trade the scythe, he did discover how to create any non-stackable item. Therefore, the glitch did not duplicate existing items but instead created new ones. Please note that the use of any such third party software to gain any advantage is against the rules in Runescape.

The glitch was performed by trading with a player, and then using AutoRune to enter the numerical value that corresponded with a certain non-stackable item to have an item pop up and be traded to the other person. For example, the number for the Rune 2-handed sword was 81, so that value would be entered into AutoRune and the player who was trading with the one using AutoRune would be able to receive that item.

In his excitement, the experimenter revealed to very few people how to execute the glitch. These players then duplicated several items, the most expensive at the time: specifically a cracker with a preset 'toy' of a purple party hat, rune two-handed swords, and dragon square shields. The most expensive item, the pink party hat, was created most amongst them. That day, though, one of these people revealed that the glitch existed.

Because of all of the pink party hats created, Jagex was not able to find all of the offenders, thus it became the least expensive party hat. With the advent of Runescape 2, the name was changed from the generic "party hat" that all of them carried to "purple party hat."

Monster Death Glitch
This glitch often involves the deaths of monsters, killed while fighting the player, but can also happen in areas with high mortality rates such as Castle Wars. The glitch makes the monster, or player, appear in the 'prone' dead position (after death for monsters, randomly for ordinary players). The 'dead' monster can still move, attack etc from the prone position while players can use skills etc. It has also happened a few times at bounty hunter. Not very often you will see it there though. As the bug is a client-side problem, it cannot be fixed by Jagex.

This Glitch also sometimes happens in the Fist of Guthix minigame.

Lean Glitch
The Lean bug caused players to lean in an unusual way. Players could move around without any walking/running animations as if they were hovering over the ground. This was caused first by leaning on the wall in the Duel Arena to spectate. Players then challenged other players in the Duel Arena while still leaning on the wall, the player leaning would get stuck in the leaning position.

Magic Carpet Glitch
A glitch appeared after the server went down. Because the player happened to be flying on Ali Morrisane's flying carpet as the server went down, the magic carpet ended up stuck around the player's waist. This was caused by the server rollback (which happens after servers go down) and the game is set to 15 minutes before the server went down.

Second floor walk on air glitch
In mid-2004 a glitch developed on RuneScape Classic where players could ascend to the second floor outside of Falador castle by standing in certain spots outside the castle and clicking a ladder inside the castle. The player would then be standing on the empty blackness outside the walls of the second floor of the castle, and could not come down. Players could walk to outside most of the areas of the free world from this point, although there were all kinds of invisible obstructions to movement in the empty space. Eventually a ladder was placed in the empty space above Varrock which allowed a player to choose to climb down to the normal play area. It is unknown if there were other areas to affect the glitch allowing to go to the "second floor" in the member's area. Many players lost accounts by getting their character to the "second floor" without knowledge of how to get down.

The glitch to get to the "upper area" was fixed after about a week, and any character on the "upper floor" was teleported to ground level when they tried to login under RuneScape 2.

Varrock Bank Glitch
The evening before the Grand Exchange was installed, a player was casting alchemy on items in Varrock's West Bank when he received the mime random event. Rather than complete it, he logged out. Between the time he logged out and the time he next logged in, the Grand Exchange was added. Along with this change, Varrock's western bank underwent a major upgrade, where it was expanded, given bank booths on both sides and having its parameters shifted considerably. When the player next logged in he finished his random event and was returned to the exact same spot he was before - which now happened to be a spot behind the bank counter.

Rabbit Hole Glitch
When a player is playing Clan Wars, and goes to the North-Western part of the arena, and stands on a certain spot, the player will go under the ground. While doing this, players can't see you on the ground, but they could see a white dot on the mini map.

Fist of Guthix minigame Glitch
This glitch occurred on the day of release for the Fist of Guthix minigame. There were many people in the same location which caused the engine to lag and players to appear outside the entry hall's walls. Another glitch, recently fixed, instantly logged players out when they walked into a house.

Weapon Positioning glitch
This glitch gives a player in a POH house to change the positioning of any weapon in the game. This glitch is most commonly use to amaze people during house parties and POH events. This glitch does not effect weapon speed or statistics. It is most commonly used to weild a two-handed sword the older way with it on the shoulder.

Falador West Bank glitch
This glitch occurred sometime from 10 April to 15 April 2008. Players could see three gaps in the roof line and the floor inside the bank was significantly lowered. 

Crazy head glitch
The Crazy head glitch was a glitch that was released with the quest Smoking Kills, where if you were a female player, had the "long" hair style, and were wearing the masked earmuffs headgear, your head would stretch all over the place when performing emotes or holding objects such as the pet rock. Some players found it just after the quest arrived when they did random emotes with that combination. This glitch has been known to happen with several hair styles and head-gear combinations.

Guthix Rest tea glitch
The Guthix Rest Tea Glitch was found in the One Small Favour quest. It was unintended that this tea instantly restored 100% of your hitpoints when you drink it. It was only supposed to boost the maximum hitpoints if you are at full health. This glitch was abused to win duels at the duel arena and to PK without dying. It was later fixed and the effects were changed to
 * Cure from poison
 * Restore some run energy
 * Boost max hitpoints by 5 if at full health.

Tail glitch
The tail glitch stretches a players trousers when they are wearing brown audience trousers, whenever they climb up a ladder.



Full screen glitch
On occasion, when a player enters full screen in RuneScape high detail, RuneScape will glitch out, distorting colors and shapes. This glitch can usually be resolved simply by clearing your cookies, temporary internet files, and browsing history, then re-opening your browser and going to RuneScape again.

Ninja glitch
The Ninja glitch occured when a player died when sneaking past the guards in Kennith's Concerns. Normally players cannot die during this part of Kennith's Concerns, but some players were able to kill themselves using Nitroglycerin, which allowed them to go anywhere in RuneScape in this position. Though it was originally thought of as harmless to the gameplay of other players, it was quickly discovered that it could be used to safe-guard items that would normally be dropped upon death since dying after using this glitch would return you to the entrance of the Rubinium mines with all of your items still intact instead of the normal death sequence. Some dishonest players took advantage of this by using the glitch to safe-guard their items in the Bounty Hunter minigame, thereby removing the risk of losing one's items to another player killer. This glitch was fixed shortly after the release of the RuneScape HD graphics.

Invisibility glitch
When getting a makeover, some players experienced parts of their character's body disappearing, often attracting much attention.
