In a multi player league once you get to the scout sim. If a player auto adjusts their roster and the team is short at a position it starts signing and duplicating the player in FA.

Can confirm this seems to be reproduced via testing on online leagues causing duplicate player issue.

On the topic of bugs and the scouting phase for multi-player leagues, teams are able to get ALL coach ratings for players by simply making the player appear on their target list without scouting. May not seem like a big issue but when combined with the fact that coach ratings are basically the same for all 32 teams and very good at identifying the best players at a position without the error rate that comes with scouted attributes, getting coach ratings for every single player is an issue in my opinion. Would be nice not to have the ability to view coach ratings unless you actually scout a player. As well as imo coach ratings should work more like the attribute scout grades (speed, str, pass block grades etc) in that they have more variability between each team and accuracy.
