I been trying to do the Super High stats training per alverdoks training guide, and something about it causes my game to crash constantly.
Does it crash on a certain dungeon level? How does the level look like at the time - are there lots of plants/monsters/items lying around? Can the game be resumed from autosaves?
If it can, I sometimes find a fair way is to make the bad crashes go away go to other levels and hang out there, for a while. Try it.
