Same problem, as I start Act 3 there's an automatic fight that wakes us up. Can't get out of it. Then I "Succumb to the ..." and nothing. Load game screen.
Exactly the same thing is happening to my game, waking up in the camp (Act3 I presume), fight happens -> game over before it ends.
The timing also makes it impossible to reach the portal (if that's the solution, nothing indicate that's what I'm supposed to do either, you're attacked by enemies coming from a portal, so you just ignore them and run to where they come from for more??).
Anybody form Larian would bother to reply the thread?
I'm not starting a new game after 70 hours, and I'm not going to try each single quicksave to see which action lead me to this. THANK YOU.
