I'm glad to see something at least somewhat similar to an issue my friends and I have encountered in our OD.
Pasting below what happened in our OD:
12 user online dynasty with the same Teambuilder presets for each user team. 12 users = 12 newly created teams with AVG Joes roster preset. Because we all had the same roster with the same names we had everyone go through and change the names of the players. Unfortunately, one of the guys in the dynasty had a weird bug occur after he edited names. It appears that some of the players duplicated, and in addition to duplicating, the newly created players had a higher OVR than should be on the AVG Joes preset. An even bigger issue is this particular user cannot join games in the OD, he gets a desync error. I'm guessing this is because he has too many players on his team? He tried redshirting these players but that did not work. Has anyone encountered this issue in OD or offline? Anyone know of a fix, this seems to be a bizarre bug. Hoping for a fix because this user cannot play any games. We're hoping he can remove these players at the end of the season through the encourage to transfer feature. However, fixing it earlier rather than later is preferred.
There should only be 4 QB's on the AVG Joes preset, in his case he went from 4 to 6, with two of them being rated 80 OVR. The highest rated QB should be 74 OVR. Second, the highest rated HB on the roster should be 68OVR, his is 73 OVR. Absolutely bizarre.
