I've got a serious problem - when I order my units to move, whether that's dragging a formation or clicking on the terrain, the units bugger off and do their own thing; they'll deploy themselves next to where I've told them to go, in a different formation.
I've verified my files, I'm playing with the latest version, and my PC can definitely handle it. It was running just fine before, and I'm not sure what I did to cause this bug - I certainly never altered any files relating to DM.
Cheers.
