So I was chipping away at the mountain crusher, and he disappeared like he had died, but didn't really die. His hit points were zero but the battle wouldn't end. Couldn't find any way out except auto-resolve, and that said I had lost, even though my army was at nearly full strength, and I didn't get any reward.

Also, the game wouldn't actually terminate when I exited, again. Still showed in task-mgr taking about 50% of cpu until I blew it away after a few minutes. But the debug.err didn't seem to be growing -- anyway, not sure if it is missing something at the end.
Edit: my quicksave from just before the battle won't load. Neither will the autosave from a few minutes before. Sigh. Looks like my large-map hard campaign is toast
