Also, the player after Persia can't play their turn.

try reverting to the pöayer before Persia - eventually you need to revert a whole turn

Thanks, we've tried that, and it seems to be working.

Correction, it is no longer working.

Not sure if this issue was resolved but we do have a similar situation.

In [url]http://multiplayerrobot.com/Game#11487/url] (and only in this particular game, all other GMR games I have are fine) I download my turn, play it and when I hit Next Turn, the game crashes while it is processing Netherlands' turn, with the "Sid Meier's Civilization V has stopped working" message.

The situation might be related to the player that would play right after me (Kevanwithana who was Netherlands) leaving. When in game, I see that the game is aware of the fact that Netherlands is an AI now (leader name is changed to William), however I saw a message saying that "kevanwithana has entered the Industrial Era". I guess the message was generated before Kevanwithana left but maybe this causes some sort of an issue.

Reverting the turn did not help the situation as when I got the new file after the revert and the previous player replaying (or maybe just did a re-upload, not sure) his turn, I still have the same crashing issue.

Eventually, we just bit the bullet and recruited someone new. That might help in your situation.

Andruh diagnosed the file and fixed it, so we were able to continue the game.

As I believe this might be useful for the developers, here is his diagnosis: "The problem is in the espionage code and occurs when a human player leaves just before the turn that his spy will try to steal technology."

After this, Andruh actually made a mod so that this fix can be applied by anyone: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=540914516
