error on PBEM replay

[nukkxx]

The replay part is corrupted, been doing pbem for over 20 years and have run into this now and then, seems to be more often lately since many no longer zip game files with the larger attachment sizes allowed now. 
Occasionally the bte itself will get so corrupted either when being saved or in transit and won't even load.  That's why I create a folder for each opponent and store the game emails until we finish, if a problem develops we just back up a turn or two and replay those.
Also avoid opening more than one game/battle file at a time, this can confuse the pc as to which folder/file it is working in resulting in these kinds of problems.

OK. So we can also keep the emails until the game ends and revert to previous uncorrupted turn if it happens ...

Yes, that also keeps us in play when one of occasionally sends the wrong file.  We may have to start the game over and we might have to start zipping files. Corruption also happens when you have more than one game window open or forget to close out the game and shut the window before sending. I am waiting for Ken to get back on whether we have start again.

No problem for me to restart. Fortunately it occurred on turn one :-) 
Let's wait for Ken. Then let me know what you prefer. 
Just suddenly coming to my mind: could the issue be linked with the fact that I created the game while I'm player #2 ? 
Maybe better if you create the game if we need to restart, as you are player #1 ?
