Glitch

A glitch (also known as a bug) is a fault in a program that causes it to function improperly. The severity of glitches can vary. The most common glitch is the reoccurring graphical stretching glitch, which causes models to stretch, but has no impact on the gameplay. More severe glitches include the infamous Falador Massacre, where a player was able to attack other players outside of a player-versus-player zone.

Rules on bug abuse
Abuse of glitches is a direct breach of the "bug abuse" rule under the honour section of the rules of RuneScape. The punishment for guilty parties varies depending on the particular glitch, and the degree to which it was abused. Minor graphical glitches generally go unpunished, while major abuse (such as what occurred in the partyhat duplication glitch), may result in a permanent ban.

Jagex has recommended that players who find a glitch in RuneScape should report it to Jagex immediately via the [ "Submit a Bug Report"] interface on the RuneScape website main page.

Falador Massacre
The Falador Massacre was an infamous glitch where a player was able to attack other players after a glitch involving player-owned houses was discovered, and proceeded to attack many players in the Falador area until he was stopped.

Noclip glitch
The noclip glitch allowed a pair of bug abusers to walk through barriers in RuneScape, nearly entirely unrestricted.

25 February 2009 crash
In February 2009, there was a bug where if your chat was on, seeing the "µ" character in the chatbox made the game crash. It was abused during player-versus-player combat.

Partyhat duplication glitch
The partyhat duplication glitch is one of the most famous glitches in RuneScape, where a third-party program was used to manipulate the game engine, allowing the creation of items.

9 June 2009 game engine update glitch
The game engine was significantly rewritten on 9 June 2009, causing a multitude of bugs to crop up all across RuneScape. Glitches ranged from nonoperational bank booths to ranged attacks only working when standing right next to a foe.

Penguin Hide and Seek glitch
The Penguin Hide and Seek glitch allowed players to spy the same penguin multiple times, allowing them to get unlimited penguin points, which could be exchanged for experience.

PvP drop potential glitch
When RuneScape used PvP worlds, a glitch allowed them to be manipulated, by using a beast of burden on a free to play, then dying multiple times, fooling the game with the wealth you have carried, before returning to a members world for kills with high drop potential.

Bolt duplication glitch
The bolt duplication glitch was a glitch where the player could enchant multiple bolts out of only a single bolt, vastly multiplying their profit.

Smuggling Dungeoneering items glitch
Several similar glitches have allowed items normally restricted to the dungeons of Daemonheim to be smuggled outside, using either teleports or a beast of burden. Currently all dungeoneering weapons disintegrate if equipped outside of Daemonheim.

Equipable knife glitch
A glitch in RuneScape Classic allowed multiple knives to be equipped, allowing massive damage to be dealt.

Runecrafting experience in Dungeoneering glitch
Upon release of the Dungeoneering skill, a bug in the Runecrafting formulas caused experience gained to be increased exponentially, prompting a quick rollback.

Guthix rest tea glitch
The Guthix rest tea glitch caused the drink to heal the player entirely, as well as remove poisoning, and restore run energy.

Ring of wealth glitch
Following an update to the ring of wealth, a glitch caused lootshared kills to utilize all player's rings, which greatly increased the chances of getting rare drops.

Dropping destroy-only items and pets glitch
A feature that allowed items to be dropped while banking caused a glitch, allowing items that normally could only be destroyed, as well as pets, to be dropped instead.

TzHaar massacre
The TzHaar massacre was a glitch that allowed players in the waiting lobby of the Fight Pits minigame to be attacked, causing them to lose their items on death.

Rat Pits Massacre
A bug allowed a player to manipulate the rat pits into letting his cat kill followers. Items dropped by a beast of burden follower were visible for the bug abuser.

Mindspike glitch
Upon release of the updated graphics for Burthorpe, the mindspike reward from the Troll Warzone tutorial was able to kill almost any normally unattackable NPC instantly, although they only dropped bones.

Adding yourself to your friends list glitch
Several methods, including utilizing display names and adding spaces before or after their name, allowed players to add themselves to their friend or ignore lists.

Kennith's Concerns death glitch
The Kennith's Concerns death glitch occurred when a player died when sneaking past the guards in Kennith's Concerns. Normally, players could not 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. Upon death outside of the mines however, the player would simply end up back in the mines, their items intact.

Player moderator forums glitch
A pair of bug abusers found access to the player moderator's forum through a security exploit.

Invisible items glitch
After the release of Z-buffering, items would occasionally be rendered underneath the floor. The items could still be clicked and picked up, but were effectively invisible. When the release of Social Slayer came out some items in your inventory or bank were invisible.

Attacking players in the Tower of Life glitch
Upon release of the Tower of Life, the basement's placement directly below the wilderness allowed players to attack each other.

Crucible Money Making Glitch
When the Crucible was first released, a glitch with the bank PIN on the money pouch let players quickly enter and leave the Crucible to double their money. This was patched the day after release.

The bug caused Jagex to do a complete shutdown of the game, making all worlds offline. A large number of players were banned for abusing this glitch.

Missing Icons Glitch
The missing icon glitch was discovered on 11 July 2012. It makes all items in a player's bank, inventory and equipment screen susceptible to becoming invisible or cut into multiple parts at random; however, this glitch never affects the numbers shown at the top-left of stackable items. As of 23 July 2012, this glitch is still unresolved for many players using Safe mode graphics.

This bug does not give anyone or anything an advantage.

Money Pouch Glitch
When the Crucible Money Making Glitch referenced earlier, above, was fixed, a glitch with the bank PIN on the money pouch let players quickly enter the Crucible Arena, paying their fee, and exited, went to the bank to refill their money pouch to maximum capacity, and got their fee back. What resulted was two stacks of their fee repaid dropping to the floor, duplicating what they were to normally be paid out only once. This could be done repeatedly. This glitch also was able to be performed in the duel arena using a similar method and was patched on the same day. This is also one of the few glitches in which Jagex publicly posted the names of the abusers on main newsfeed. http://services.runescape.com/m=news/a=376/bug-abusers-banned Estimates on the amount of gold duplicated vary from 800 billion to 7 trillion gold. Prior to being virally leaked, people were known to have multiple scripts repeating the glitch since at least 20 June. It was patched on August 5, 2012, and all accounts were rollbacked to August 3, 2012.

Graphical stretching glitch
Graphical stretching glitches, where a part of a model stretches in a way not intended, are one of the most common types of glitches in RuneScape.

Minimap glitches
Minimap glitches are common in RuneScape, including black or white backgrounds on the minimap, black sections, or failure to display the minimap all together.

Trivia

 * In the Evolution of Combat beta, players could directly report bugs in the game via the report button, which is usually only used to report players. In the report screen, some RuneScape "bugs" like spiders and kalphites would regularly appear and players could click on them to reduce them to a green splat.
