I have 8 Units including the Champion in one of my villages (Serrane). I can move every unit out of the village by itself except the timber warg. When I try to move that unit by itself it moves one field and then runs back into the village (sometimes moving backwards, sometimes turning and going back).
(Seems the timber warg is a little afraid during that turn... 
Is it meant to do that????
If I move the timber warg together with another unit it leaves the village without trouble.
If I move the timber warg onto another unit already outside it leaves the village, but does not join that army and instead stays seperate after the move.
If I move the Champion out of the village by herself and then try to move the timber warg somewhere else it moves one field and turns around and then joins the Champion?
After I have "tricked" the timber warg out of the village, everythings works normal again and the timber warg is an independent, self confident unit again.
Note: I tamed the timber warg with the Champion, but that was quite a number of turns back and I tamed other beasts inbetween and these units have no problem leaving the village alone.
