Error When Editing Lineup

Same thing happens to me and I get that same message and idk what to do

Same here. I can't do anything to my line up. Let me know if you find a way to fix it, any help would be appreciated. 

Im also on old gen and not able to make any lineup changes without getting kicked. Just bought a bunch of new promo cards and cant even use them. Please this fix this asap EA. 😑

Same, xbox one x. Right after adding new cards from yesterday's drop.

Same here, it's gotta be a EA glitch that they need to patch. Probably has something to do with them downgrading peterson? but only they would know. Interesting that it's only old Gen. we bought the game so they should support us. 

Agreed, this has been going on since Thursday for me and still having the same issue.  Also if you have a look at the new 98 Athletes players their last ability buckets are empty and no ability available to select. 

Both Calvin Johnson and Ed Too Tall Jones last ability buckets have no abilities available in them. It's empty

Wow, thanks for the heads up, we gotta be careful what to buy or not cause not everything is the same for us, I notice abilities. I'll watch those Asa cards, if we ever get to play again:) so far I only got a.edawrds cb, and Jimmy g. Te. Hopefully this isn't it for us,,,,,,,,easter/draft/golden tickets/fan appreciation..... and if I can't finish, then I ain't playing ever again.

Where's the comments from yesterday that said try this:

And were missing out on season xp now from dailies 

Generate best lineup so you will at least be able to get your dailies and solos done. Not ideal but worked for me. You'll at least have a team to let you play.
