Crash in Act 6, The Ridge map

Like in topic title, the game client crashed shortly after entering this area. I tried quite a few times to see if I can find anything, after last retry this window popped up:


Anyways, I can't progress further atm because of this bug :<

edit: OK, waiting for a bit, and reloading a map again seems to have solved it... Now I'm able to run on the area without problems so far... Maybe it was a loading bug of sort...
