Sooo about this 10105 error...

From what I've picked up around the most relevant explanation seems to be that it happens a lot after you DC during an instance—

—so is there any way to fix this? At all?

EDIT: Nevermind, it returned to normal somehow after about an hour and 15-20 minute ish :'| Would've been nice for them to say something like 'you've been locked out from the game due to mid-instance DC' instead of scaring a player to near ragequit with no explanation other than some vague 'connection with world lost' statement... :'(
