So, this time through, I was making backup saves every 10 games so I wouldn’t lose much if it did corrupt. Because of this, I was able to pinpoint the cause:
when I get the challenge from the reporter to break the rookie goal scoring record, the next game crashes.
I scored more in these few games, so I got the challenge with 35 games played instead of 37, but the challenge is what triggers it. Same thing every time. I always choose the Promise response, so I don’t know if that matters or not, but this is the one constant. Can anyone else verify?
