I had an idea for fixing the rotation, I posted it in Requests in case no one had already thought of it. Yes, that would be sorta cool to have the different races. Specific to my map, though, I was looking for something more along the lines of "supply wagon", the sort of thing you'd see in caravans.
I have a feeling this is a sorely needed model for many people, so you'd be doing more than just me a favor by completing it.
