[Wdll]

Since, apart from finishing a battle, there is no button to tell the game, " this battle will not continue cause the other guy doesn't feel like it", how does the game know that the new files you receive from the other guy for a new game on the same slot, are new and not going to affect the new game in the way mentioned in this thread?
Should both sides just delete the files, start the game, quit the game and then copy the new files?
