This is an oldie - at least for me.
Spain is unable to complete diplomacy phase, because of popup stating:
"Waiting file from Russia for the Battle of Tangier"
Siege battle at Tangier (Morrocco, right), Russia controls.
Corps of Morrocco in city. Spain siege gives breach.
1.round: Spain sends battlefile. Russia returns.
2.round: Spain sends bettlefile. Russia returns. Spain is broken.
There is no 3rd. round and the battle ends.
The returned battlefile is deleted by the spanish program.
Spain has no other battles.
Spain does 'End current phase'. Games creates spanish combat file and sends to all.
Russia load spanish combatfile, and game moves on to next player.
All fine so far - perhaps ??
Now Russia, who is the host, creates backups and distributes.
Spain loads game from backup. Loads turns from other players.
Start his own first turn after backup.
But he is not allowed to finish turn, because of popup as decribed above.
Why is this a gamestopper?
Because Spain had no problems before the backup and could finish his phases. And obviously so could Russia.
(I know this from an earlier game, which was abandoned)
When recieving the backup Spain overwrites his own game, and runs into the popup.
So any new backup does not solve the problem, only repeat it.
I believe this comes from Russias program, which does not finish the battle properly,
but still allows loading of spanish combatfile, and then moves on.
When - at some later time Russia creates backups - this hidden unfinished battle comes to Spain and stops the game!
I have more files on this and can e-mail if requested.
