Game Crash Necromancer Single Player

I’ve been trying for a bit, but with one specific character it keeps crashing. It only happens in the very beginning of act 4 when approaching Tyreal and Imperious. When Tyreal begins to speak, the game shuts down. I can move the character into campaign mode and everything works fine, but I cannot progress in the storyline.

If you have Crash IDs, add the details to this thread…
