Damn I experienced a crash when I tried to complete a quest.
There was a cutscene but I couldn't see it because it crashed when loading it, so I'm quite pissed...but upon my return in game I just saw I LOST another quest from my log...
"The Beginning of his Notorious Reputation", which is received automatically in Cultists' refuge is now gone from my log, and i can't get it back.
I opened a ticket with Frogster support, I really hope they'll get back to me tomorrow and that they'll be able to recover my character or give me the quest back...
In the meantime I stopped playing to ensure there's not much difference in my character on their server compared to before the crash, maybe it'll facilitate recovery...
