PBEM basic security OOB Warning

[Cross]

New ver 4.0 feature:

12) When playing PBEM in basic security mode the game will now simply warn players if the OOBs differ from the original without aborting the game.

I just started a new PBEM campaign and my opponent got the 'OOB warning' when he opened my files. I also got the 'OOB warning' when he returned the files to me.

I know I've never fiddled with my OOB, because I mainly PBEM, and my opponent says he has a new install of the game.

Can anyone verify this same error message, in a PBEM campaign?

The good news is that this just sounds like a 'faulty warning light' and won't keep us from playing.

Thanks,
Cross
