You might want to put text to explain where you see a bug?
My problem is that the stacking as it is makes it very hard to select a unit. I can't understand the system at all. When I get two units in the same tile, They can either be one by the other, looking ugly, or merged with a bigger base.
If there are several units, not in one stack, they should really be in different positions inside the same tile because it's a pain to select one. If you manage to get two units in one place, how can you select the one you want if they are not tiled?
Note it quickly becomes unplayable when the unit that's standing in the way has 0 move (likee the default warriors and scouts), so it's never able to move out of the way and can block all units that go there.
