I've had several crashes today on Orcs when trying to move units into my town, I usually get a big lag spike before the crash. I managed to grab one screenshot of the ntdll.dll crashing, unfortunately, the logfile it sapposedly created wasn't in the temp folder it said it would be in. I also managed to crash mithril.dll after logging back in and trying to move the army and resources to town again. The mithril.dll is generally what crashes for me, so I was surprised to sell ntdll.dll crash. Again the logfiles weren't where they said they should be to post =/ so this probably doesn't help much....
