2 Replicable Ways to Cause a Desync in "Play a Friend"

I am in a league with ~150 people on Xbox and Playstation who play entirely through the "play a friend" mode and have found that whenever a user attempts to use a custom playbook on both offense and defense a desync will occur, typically before the first play after the kickoff. There is no desync if only 1 custom playbook is used.

Additionally, on two occasions I have had an opponent attempt to adjust the wear and tear substitution sliders during a game in a pause menu, only to have a desync occur before the next play.

We really hope these can be fixed before our season starts because we log all statistics from every game and it is incredibly detrimental if we were to experience this error.
