I'd like to know more about these crashes, and where they are from. It's strange that the dungeon is regenerated, since it should be using the same random seed. I'll look into that too.
I can see an autosave feature being really useful, but haven't found a particularly good time to do such a thing. Maybe every 100 turns? Every game day? Upon elevation change? I'm not sure. Those people who save scum will do so regardless, so I'm not worried about enforcing permadeath to an extreme extent.
Tl;dr - yes :)
