First shot against a lizard type with a scoped rifle caused CTD. Tried reloading a save from the same turn and it immediately CTD. Tried reloading save from a few turns before and it immediately CTD. Tried save from outside encounter, another CTD. I know there's a thread for general "can't load" errors, but my first issue was in an encounter after I took a shot. Had fun blowing stuff up with aircraft until then.
