[1.0.9 Beta] Somehow I'm producing wargs even though I'm playing kingdoms

This happens if you take over an Empire city that has a Warg Den already built.  Same goes for the monster units like Demons.  Probably is a bug but that's the cause as far as I know.  Seems to give the city "as is" without any checks to see if it should stop X or change Y (like whether you can still build "1 per faction" buildings).

I had the Magnar AI attack me with horse riding soldiers last game...
