Game Crashing 50% of the time I cull an enemy (Abyssal Lich) with Soul Offering or Bone Offering.

I think the title is pretty self explanatory... Please fix your damn game. I have lost 5 diferent corruption nexuses because of getting DC`d (game crashes) whenever i use the offering spells and then I come back to game but im back in my hideout with the map having failed..... [Removed by Support]
