Error when trying to change lineup

Hey AspectKJ​,

There are a couple things we can try that might help with this. 

First, if you can pull up your Item Binder, check and see if there might be any gaps in your lineup. You should be able to add players to your starting lineup when you select them in the Binder. If there are any positions that don't have a starter, try adding someone through the Binder and see if that helps. 

If you're still getting the same error after that, it might be due to upgrades or chems on one of the players in your lineup. You can try removing these on the players in your lineup by selecting them in the Binder and moving over to the Upgrades tab. Try removing the equipped chems and upgrades and see if that helps with the error. 

If you're able to give it a shot, please let me know how it goes. Thank you!
