Playing through Campaign Mode, using the Move By Detachment option, and if I cycle through a detachment of artillery pieces (e.g. Basilisk or Bombard, haven't seen it for Manticore or Thudd Gun yet) without doing anything with them, the game freezes, requiring it to be killed at Task Manager. Windows 8.1 machine, don't have specs as it's a generic Best Buy POS.

I know the simple answer is "Don't Do That Then", and I've been prodding my artillery to move when I remember, more worried in case something on the enemy's side does it too and leaves a mission unplayable.
