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.
