Captured this wildland / city / thing last night and it's a level 7(?) village with no specialization. It had no troops in it and my game bugged so that no units could move and the turn button wouldn't work. Reloaded a previous save and the same thing happened. Captured the city and saved, then loaded that save and everything works, but the city has grown to level 8 now, has no garrison, and no specialization.
I did some digging and it seems that others have experienced this in FE too.
