I've noticed this while playing the Battle of Toba-Fushimi, Normal difficulty. This bug was not happening, at least as far as I could tell, a few days ago. I haven't checked to see if it's started to happen elsewhere in the game.

Basically for the first couple of minutes of combat, everything goes fine. But after my rifleman units on there eliminate a couple of enemy units, about half of my rifleman units start refusing to fire. If I tell them to fire at will, they won't. If I tell them to direct their fire at a specific enemy unit, they'll just sort of keep walking slowly towards that unit without ever stopping.

This is ruining my newly-purchased game. I would like to see this fixed, and I would also be interested in knowing if there's something I can do with Steam or something to clear the bug myself. Thanks!
