The Game Worlds are being rebooted to solve various issues players have been experiencing, with content such as Vorkath, Tears of Guthix, and Grotesque Guardians.
We'd like to apologise for the inconvenience of this, and the short notice.
The issue seems to be related to how long the game worlds have been open for without a reboot, with an entity limit being hit. Normally this wouldn't be a problem because we do a game update weekly. Following on from this we will be investigating that issue itself to prevent it happening in the future.
As of 16:52 GMT, this reboot is now complete.
If you are still experiencing bugs, please report them via the in-game report button located at the bottom of your chat box. In other news... Happy New Year everyone!
