Yep, K beat me to it.

One thing I remember happening in STW/MI was a bug with assassins. If I killed a general in battle when he was targeted by an assassin, trying to move the assassin on thefollowing turn would cause an immediate CTD on the strategic map. (Apparently he couldn't accept the dishonor of failing to kill the already dead general, so he terminated the program instead--virtual seppeku.) If I left him alone for a turn, all was fine and his honor was intact. I believe this was fixed in the final patch though. I vaguely recall trying to cause the CTD after the final patch and couldn't get it to do it anymore (whereas it was a 100% repeatable CTD before that.)
