I newly installed most recent versions of Ascension and Sola.
I have had two crash bugs I haven't seen before - once when I enter the defunct Temple of Bhaal before speaking to Nyalee - it looked like the Skeleton Mage or Cleric was casting something that made the game crash. My guess is it was the Mage, because when I later dropped 3 adhw on his head and killed him before he got a spell off I didn't crash.
The Yaga problem was similar - it looked like he was casting something and the game crashed. In both cases it looked like it was Sunray - it was the column-of-light 3d effect, then boom.
Anyway, new to me as of this install. I think I have saves just before both encounters.
