does it solve your problem if you do it?

I lile very hard, 2 Vs 2.     If the AI attacks your ally first, it may become challenging indeed.

No, I just selected the mesh and armature, rotated it, and then exported it.

Yeah, in DE, capturing has been modified quite a bit. So, the more Civic Centers you build or capture, the less loyalty they have. It's called the 'Public Order Penalty.' As the empire grows, your Civic Centers are less loyal, essentially. It's part of self-balancing I'm trying out, to see if I can reducing snowballing. Building Temples and capturing Shrines reduces this effect with the 'Public Order" bonus. This is all crucial, because most other buildings have their capturability removed, except the Civic Center. Capturing the Civic Center is the primary focus. 

Oh, so they appear in DE (though quite differently than I suggested) and in normal maps they are the "temples with their own roots" that I mentioned in my first post. Thanks for the explanation !

Looks good
