I'm experiencing this game-breaking problem.
2 Human Players
6 AI Players

1. Turn 24 (green flag but says the game is not fully synch) I have a fight with Vodyani, but the fighting never starts when you click to start and never resolves, therefore I'm not able to end my turn. (Saving option also stops working)

2. If I choose to end the turn without the fight and going to turn 25 the game syncs again, but than if I choose to fight there's the same glitch, the fight wont resolve. (Saving option stops working)

3. If I choose to end turn 25 without a fight again, from there on the game keeps on a permanent de-sync (Saving option stops working).

We've tried reloading the game many times, but since this first fight with the Vodyani started, the fights started to bug (not resolve) or the next turn becomes de-sync no matter what.
We have also tried to go on from turn 25, but the next turn always become compromised by de-synch.

This happened everytime we tried to start over turn 24 or go on from 25. We had to stop playing beacuse it wouldn't synch no matter what.

Everything seemed to go wrong after what should be the first fight with Vodyani in our game on turn 24.

Had a similar problem on turn 125.
