Posts from Desynchronization in the multiplayer mode of Heroes of Might and Magic V: Tribes of the East.

We tried playing with a friend on a local network. For the first 3 weeks of game time, everything went smoothly without any noticeable bugs, but then something started happening. I finished my turn and clicked on the clock, and it told me that it was my friend's turn. Well, 20 minutes passed, and he seemed to be thinking for a very long time. It turned out that he was also getting a message saying that it was my turn. In the end, it showed me that it was his turn, and him that it was my turn. And that's it. The game just froze in place. It wasn't exactly a crash, but nothing else happened.

Exactly the same problem. I'll provide a bit more detail:

Initially, we were playing via an Ethernet cable. The settings were: Simultaneous turns, Ghost mode. Towards the end of the first month of the game, strange animation lags started occurring during the computer's turn. As a result, on one computer, the loading bar appears for a few pixels, and on the other, there's not even that result; messages within the game's chat stop being received, and then the game either freezes completely, and sometimes (about 10 times we tried to load it) a message appears saying that the player has disconnected.
We tried to finish the same game by loading from previous saves, but at the same turn, everything repeated. An attempt to finish the save through Hamachi was unsuccessful.

If anyone has already solved this problem, please share your solution.

It happened to me once; I was playing through Hamachi with an opponent, and at some point, the connection started to degrade, but there was no disconnection. Then, the opponent told me to finally set up my units because he had attacked me, but I couldn't even see him on the map. In the end, we had a 2-3 day desynchronization, but we couldn't load the game.
I think there was a similar problem on Ubi.com a long time ago, but I don't know how they solved it or if they even solved it at all.
It hasn't happened again since.

Gentlemen, please disable your antivirus and ping to confirm. Also, I noticed that if the Windows versions match, there are no problems, and whether it's x-64 or x-32 also has an impact.
