9 June 2009 game engine update glitch

The 9 June 2009 game engine update glitch occurred on 9 June 2009 at around 16:00 UTC after the RuneScape game engine was significantly rewritten. Just minutes after the update, however, players were experiencing a huge variety of bugs, and soon the RuneScape Forums were overloaded with bug reports and confused players. One of the earliest reported glitches was that players could not run and eat at the same time which, according to Jagex, involved accidentally removing a feature that allowed the player to perform two actions at the same time.

Banks
Many banks became inaccessible, the most notable one being the Grand Exchange bank. If a player attempted to talk to a banker, they would get the error "I can't reach that". Zanaris bankers would give players the "Nothing interesting happens." message when they tried to use the bank.

Disabled Attack Styles/Non-Retaliation
All of the non-player characters were unable to use Magic or Ranged attack styles, and a number did not retaliate to a character in any way. This led to players successfully "solo-ing" the Corporeal Beast, going through the Fight Caves extremely fast, and killing the bosses in the God Wars Dungeon, as they had no worry about taking any damage.

Other glitches
Some of the glitches reported:


 * Crystal chimes stopped cleansing warped creatures.
 * While scaring away the dog in Varrock, you pivot sitting down then scare it away. It has not been fixed yet.
 * Players could not remove their armour while running.
 * Evil Trees could no longer be inspected.
 * Players could only train Ranged or Magic standing right next to a foe, and the Dragon halberd could not be used to attack from behind an obstacle or a space away.
 * The player-owned house doors disappeared, except for the doors at the entrance.
 * Ava's accumulator didn't work.
 * Players could no longer train Hunter.
 * Players no longer automatically go west when they light a log.
 * You could get free Firemaking skillcapes if you had 99 firemaking.
 * Summoned familiars became invisible.
 * Players could no longer bless gravestones.
 * Magic darts didn't work.
 * Void Knights became invincible.
 * Penguins could no longer be spotted.
 * Triggering a trap in Pyramid Plunder would get you stuck and kill you in a matter of seconds.
 * Players could not complete random events, or leave the random event area.
 * Players could not set up the Dwarf multicannon.
 * Bankers were seen facing sideways.
 * Players could no longer jump on the Basalt rocks to get to the Lighthouse, or jump on the Stepping stones to get to the Tears of Guthix minigame.
 * Random events were appearing in the space where the bankers stood at the Grand Exchange.
 * Hopper controls in Windmills, including in the Cooking Guild, no longer functioned, and "couldn't be reached".
 * Teleother spells could no longer be cast.
 * When you tried to regularly bank a banker it said "This booth isn't in service."
 * The rope swings in the Brimhaven agility arena "could not be reached".
 * Rock crabs would appear when you walked over them, but immediately disappear, making it so you could not kill them.
 * Elementals in the Sorceress' Garden would not teleport players.

Aftermath
Some players went so far as trying to get people to riot in protest. With the new "rest" feature, "sit-ins" around the Grand Exchange and other banks became popular.

Even after Jagex attempted fix the glitches, other bugs continued to appear. After a fourth system update (with a total of six for the day), most issues seemed to have been resolved.



Many players are complaining about the fact that Jagex has refused to roll-back to a previous state before the update, and to punish the people who exploited the glitches as it was a violation of the rules. Even though Jagex had said that they would not need to do a roll-back, they did roll-back World 64 which crashed on the same day.

It has now been reported that this was caused because the entire game system had been reintroduced to improve the game engine it was said that after 6 years of updates the foundations were very messy and this tidying up allowed it to perform more easily. So, contrary to popular belief, the run update wasn't the reason for all the glitches, the new game engine was. No one was banned after these glitches according to the recent development diary. Jagex had received so many Bug reports on the RuneScape Forums that they had to close all the threads for a while so they could read and sort through all the reports.
