The answer then is yes. I've had the "luck" of having at least two or more campaigns going at once
vs. the AI, and I've
never had an issue with any patch upgrade affecting my campaigns for either game.
So you will be good.
But just as a general reminder load your patches in order and take the proper precautions before downloading the patch during an active
PBEM game. Don't remember exactly what it was (Finish it I think before downloading.) but, Don makes a
point of reminding everyone of what has to be done before downloading the patch anyway in
BIG BOLD LETTERING.
Have fun and enjoy the game(s)
with confidence!
Regards,
Pat
