This save should be a turn or two before a crash to desktop. I couldn't find anything immediately obvious to cause it. I did notice that Hyborem had been summoned but just sat for many many turns outside a barbarian town (eventually captured by Bannor). But no matter what he just sat there. I tried deleting him but that didn't prevent the crash either.
Please ignore the gameplay thus far, it's a save from "a friend".
