HoM&M V: The Shadow of Death doesn't work in a local network; the save file is corrupted. Auto-translated

Hello, we decided to play "Tribes of the East" over a local network, and we didn't have any problems with the game or setting up the local network. The problem is this: During the game, I experienced a connection interruption, and our game was interrupted. When trying to load the save file in the game on my friend's computer, he received the message: "You are not mentioned in the save file of this game". We both have the save files. When my friend creates a room, I get the same message. I've searched the internet, but I haven't found anything helpful. I'm begging for help with this problem.

If you have a save file from before the crash, simply send it to your friend and have them replace their current save file with it. And voilà, everything will work for both of you.
