Anarcopie and I have been playing a simultaneous game and we have found some odd things going on with freeze mode. A number of times one of us could move first and the other was still frozen. It's easy to think it's just in our heads or something, but we finally caught it at a clear cut instance and I took a bunch of screen shots as we talked about it over chat.
For turn 39, we were both moving and talking at the same time. Anarcopie ended his turn first and I logged out and waited over 12 hours before going back in to end my turn (so I wouldn't be asleep when it started the next one). After I ended my turn, it said the freeze would last for over 4 hours. Five to ten minutes later, Anarcopie started messaging me about the turn. I left the game I was playing.
Our game still showed it was frozen and on turn 40. I went into our game. He had already attacked a city where I had two heroes. He started talking about the turn. When I told him I still couldn't move, he was really surprised. I watched him move several units. I tried to move again, but the game told me that my turn was frozen and it wouldn't let me move. It wouldn't let me pick up items (he had killed one of my heroes, but another of my heroes was standing in the same place and I tried to have him pick up the items the first one had).
Then he said it wouldn't let him move anymore and showed him frozen. At this point my freeze time was down to around 3 hours and 30 minutes (see screenshots for details). Now we were both frozen on turn 40 (though he had already moved on turn 40). I could even pull up the battle dialogue, it showed 3 attacks he made on turn 40, the very turn we were on and now both frozen in. At this point, his screen showed more time before the freeze would end than me. He showed over 4 hours (around my original amount of freeze time) but mine showed around 3h30.
I tried a number of different things to see if I could affect the state of the freeze. I logged out and logged in--with no change for me (I do not remember if that might have changed him from unfrozen back to frozen, but I didn't remark on it causing the change at the time). I closed my browser (Google Chrome) and reopened it also. Finally I rebooted my computer (after he was already frozen). As far as I could tell, none of these made any difference.
I have about 16 screenshots taken while it happened. You can view them here:
