There seems to be a problem when saving the game with units that are damaged.
If the damage is sufficient for the unit to have lost a figure, ie be down to three soldiers and then saved and the game closed, when you come back to the game later/the following day, the unit is now a three man unit permanently with the attack/defence etc reduced accordingly. It cannot heal back to a four man unit.
It seems to be ok if you have all four figures in the unit. You will get the unit back to full strength.
Ive had this happen to me two or three times now.
Ill try and get a couple of saves that reproduce the problem. But I thought Id mention it and see if anyone else had a similar problem.
