I have the same bug.It's okay already.
In my saves, a turn timer appeared from somewhere. I did not understand how to disable it, I tried to run saves as a network game, but there seems to be a ban on changing settings. Fortunately, after checking the saves 10 moves ago, I made sure that there is no timer.
10 moves is not that much)
sometimes after loading a game, a timer appears out of nowhere. I don't even know how to disable it.. and as for Avaddon reloading a few turns back generally works (but its frustrating) (and 1 min 30 to play a turn is not much)
