Bug reports.

Found a bug: I took a castle from the AI, but then left it empty. The next day, the AI ran into the castle, but the color didn't change. Another day passed, and it ran out of the castle and recaptured it, as if nothing had happened. When I opened the castle, I saw that the AI's hero was inside, but the castle was still mine. This happened on Mininoстальгия, and it only occurred with the purple AI.

This happened around days 116-122.
