Just finished Stones River and all the officers that were injured in the battle are not in my barracks anymore. I think this happened before, too, after Fredericksburg, so maybe it has something to do with multi-day battles interacting with the officer replacement function of the mod? Not sure if this WID and injured officers have a chance of dying and I just had bad luck, a vanilla bug or a mod bug, but just thought I'd note it here in case it was the last one.
