I think they should be on both, purely for the ease of saying that those are all of the buildings in game. Otherwise I’m a bit afraid that we will lose some players as they check the buildings in hopes of finding info on fruit mixer.

I might be totally off the mark too, but I don’t really see the harm in production buildings being in both categories, since there aren’t that many buildings to begin with.
