team diamond sets

my team diamond sets don't work again, whenever i try to finish the set, it just disconnects me from the servers, im on pc, is anyone else having this issue?

Yes, and I have a ticket on the EA forums under general discussion. It’s at the top now. I’m getting it in the TD and also the MF sets.

This has happened to me with other sets. Sometimes it is because I've tried to put a card from my lineup in it or it has AP on it. Normally, you can't add those cards, but it's EA, and sometimes you can add it but then can't complete it. It glitches out. It has also done this to me when I don't have enough cards for a position in your lineup (for example, you need at least one Center). I only noticed this because I had put locks on all of the guys in my lineup, but with locks on they don't count as positions in your lineup. Basically, just a few of many things EA has not fixed with their game.
