When I was manually hosting games before llamaserver appeared, rollbacks were almost a no-issue. 1) Make sure that nobody has unfair advantage (ie not use the 2h files for first turn that were sent after players saw the outcome of battles in that turn). 2) Tell all the players to completely delete game files for that particular game. After that you just host the backup copy with old 2h's and send them as usual, nothing will be messed up.
