I thought I'd put this up since it has been happening since 0.75 when I grabbed the beta, I've been declared war upon by Karavox of Kraxis, he's decided that my city would be better off being under his control, he casts broken loyalties on it, since there's no attack on the city and my stationed troops are standing outside it I'm assuming this is what's happened. Anyway, I send my troops back in to take the city, however once I've got my city back I can't finish the turn, I can finish the moves of my troops, change the build queues, still not able to complete my turn. At this point the only work around I have is simply not to have Karavox in the mix, although I have not as yet tried to raze the city once it has been recaptured, I like my city.
