Insurgency ???

Hello,

Well this one was fun HAHAHHAHA

So Czechoslovakia (computer player) was down to 2 provinces, Zilina and Cosice, with a single infantry in Zilina. I was never at war with them, Germany had taken most of their territory. Yesterday I started to hit Germany in that area and earlier this evening took Pilsen (Czech core province) from Germany. I had a single, level 1 light tank in there and have been checking in every hour or so to make sure nothing was coming near it, which at last check it wasn't. When I came back on the last time, my unit was replaced by the same unit belonging to the Czechs at 100% strength and the territory had flipped to the Czechs. I control all the territories in between Zilina and Pilsen, so unless their tanks became air mobile (LOL), then something happened that I cannot explain.

Is this a bug?? the computer "cheating" ?? or some sort of insurgency factor built in for provinces with low moral and low number of garrison units ?? and yes, I've tried re-loading a couple of times to be sure, even closed the browser completely once.

Edit: Pilsen was at 68% morale, when I just looked again.

What gives?
