hey ho TechSupport! :)

We played about ~90 rounds and restored the game before that a few times because we played over multiple days. Now we had some issues where we had to resync and suddenly my friend had loaded another state of the game than i did (he was at round 90 while i am at the resynced round 98). So we closed the session, restarted the game and restored an Autosave-file from round 97.
As we were in the loadingscreen the state you can see on the Screenshot i attached occured and did not skip. It is stuck. Every save file based on this session has this error. It won't load and is stuck on "Downloading" while i am waiting for him to finish it.

We already tried to send each other the save files but that did not solve the error. For now we gave up and so i created this thread. 

I hope these information will help you. Thank you for your time. Have a nice day :) 

Have you tried to load a save from before the issue? If he's stuck at turn 90 for instance after your faulty loading, maybe reload a save from turn 89 and play again from there? Just thinking out loud, but it might be the source of the desync...
