Just another note cause I think this is the same bug. Had this happen today: Use the turn to polymorph Diggle dies to trap Character levels up Close skill menu Game crashes
And I just had it happen under Win7 64-bit... Was clearing out a zoo with Runes of Exploding (remarkably effective ) - last critter dies to the ground fire (what is meant by a spell mine, I suppose) and triggers both the zoo reward and a levelup. I was probably in the process of moving, too, though it's hard to tell sometimes... Had hit = once for the animation speed boost, as well. May also have been in the process of trying to autosave, as well - no autosave available so can't continue. Oh, well. It's a Roguelike, so no point getting annoyed at having to start over.
I'm having the SAME issue. It always happens when I kill a enemy for a quest, the game crashes. I run on a windows 7, with the steam version, some steam workshop mods and both RotDG and YHTNTEP.
