I've played Civilization 5 in a co-op multiplayer session two nights in a row, and both times there were no saves. My friend hosted the game and had it set to save every turn, but still there were no saved games made. Since the game crashes or drops one of us at least once every night we play having saves is rather vital.
This has worked before for us, so I wonder if it isn't the result of one of the latest patches. We are using Steam, so the game is up-to-date with the latest version. A Google search only turned up reports of the multiplayer save issues from when the game was released, but nothing more recent.
What is the culprit?
