I just played a couple turns of a campaign and everything is awesome, except for the AI. Just getting 3-4 infantry units into a single line formation can be a hassle. The units get stuck in a bunch attempting to make there way towards there designated spot in the formation. Getting calvary to halt or stop is difficult also, as they will still charge, even after frantically hitting the halt button.
I hope this is fixed in the final v1.7 release, because it is extremely annoying, especially dureing bigger battles.
