As there are so few races open at the moment, here is one I was going to use for the middle earth series but decided not to as I don't know how to make buildings look like buildings - just blank walls. Fences with 2 tags and thick walls are uncrossable.
Janands (and others) I don't understand how you were able to get through the uncrossable fences. They are set with 2D boundaries which I can see in the conversion map image, and I can't cross them myself.
@Billo I think the simple answer is: jump. I see now that I can't cross at ground level, but I always jump fences, and that seems to work on the uncrossable ones here.
