It is now a few hours after the hotfix. I am stuck in a game where a player has stopped moving, and the turn has not been passed nor has he been replaced by an AI.
In other words, the situation seems to be at least as bad as it was before the hotfix.
Update: After about 20 minutes of waiting (yeah, I'm patient), the system finally kicked the frozen player, shortly after declaring that he had lost connection.
Thanks for the info. We will look into it.
