Thanks Guys!
I didn't expect to get past the first round, never mind win the thing.
I know Marv had some sub issues, but I changed with my tactics at 2:59. I'm lucky I did, as I would have been losing on tactics for 60 minutes if I didn't, and that might have been enough for Marv to over power my season 1's regardless of a few players being out of position.
I don't know if this has anything to do with the match engine. But, yesterday with this same team, I subbed on a striker to go in goal in a friendly. Went on to lose 6-1. I don't usually use subs, but it could have been a lapse in concentration when I set up.
