I’m having the same problem. Have about 90 hours in before this update and it has never crashed. Now I’m crashing after about 5 minutes in game and i’m nowhere near any of the karka events. Travelling to lions arch crashes it for me.
EDIT: Now it’s just completely unplayable. I can’t login for 10 seconds without crashing. I don’t want to do the karka crap I just want to PLAY the game!
