[Bug]AI builds crazy amount of hovels on captured minor faction

I have a savegame file, but it was too big to put on pastebin.  So, I'm not sure how to get it to you.

Anyway, in this game, I found an AI town that had 31 hovels built on it.  It was still level 1 and produced crystal, so I assume it is a captured minor faction.

As a bonus, in this save I have all 5 forge pieces, but I can't seem to end the quest.  It looks like that one was covered in another thread, so I won't go into more detail unless you need it.
