In the first mission of the German campaign, I lost the commander of one platoon. In the followinig turn I combined that squad and about 10-15 sec into the action phase I could see command coming back to the platoon as command lines turned red again. No one in the HQ squad is an executive officer, 2IC or such, so I don't get why this happens. I have a save and the bug, if it is one, can be replicated.
