Ok, this got me thinking about real war fare and the like.
The new Idea is that for a base to get the automatic resupplies, it has to be adjacent to a friendly base.
I.E. No enemy bases can be imbetween them.
So if the bishop push a point up into Knight land, the knights then attack low and at the sides of the bishop peninsula. Anything isolated from bases which are adjacent one after another to the HQ does not recieve automatic resupplies.
However, you can do resupplies Via m3 or C47 still.
