I came here to see if anyone had reported this. I experienced this yesterday with a friend in an online dynasty.
I am on Xbox and he is on PS4. When we were trying to manually progress our players at the same time, it would occasionally tell me I didn't have enough points (when I did) and it would change the team logo behind my player to his team logo. I would then have to back out and go back in to upgrade more attributes.
This only happened when we were progressing at the same time. We discovered that if one player leaves the progression screen the bug stops happening for the other.
