Wall breakers and walking through buildings.
At the moment now, if someone masses wall breakers on you, they will choose a wall to attack and if any buildings are in the way, does not matter, the wall breakers will walk through them.
The issue.
I think this is a little overpowered. Wall breakers (and possibly goblins too) should have to have a clear path to the wall to break it. Ie only destroyed buildings or empty squares to walk on. Not just walk right through intact buildings as if they don't even exist. I think this really needs to by fixed.
