A bug is an error (in performance) or a flaw (in design) in a game which prevents it from working as intended. This includes things such as graphical glitches, players' input being processed wrong, or other features not working properly. Bugs are fixed in game updates.

For a list of current known bugs, see Category:Bugs.

An anomaly, on the other hand, is when it isn't explicitly known how a feature is intended to work, but it's inconsistent with the rest of the game. For example, the poison clouds created by Yelks when they die is not decreased through poison protection; it's never mentioned whether it's supposed to.
