HUT Corner Stones 89 Card Went Missing?

I googled this issue and saw a post on here from 4 months ago about a similar thing happening, but no real help on how to solve this.

Right here - Cards from sets going missing. | EA Forums - 5037405

Basically I've been doing the HUT Corner Stone sets for last couple of days and about 3 days ago I made my 3rd 89 rated card which was Bobby Clarke (Because I had Kurri and Bucyk already). When I went to make a 92 rated Rick Nash and tried auto filling it added just 2 cards it was Bucyk and Kurri, then I removed them both to try adding them 1 by 1 it showed all of the cards, but when I got to adding the last one it would show something like "error adding card" at the top of the screen. I thought maybe the EA servers are down, so I decided to do the set a day after and when I went to do it my 89 Bucyk card was completely missing. It's been like that for 3 days now. I've tried restarting the game many times, I checked all the possible sets and the card wasn't there.

I need help ASAP because the event is ending soon and I feel really scammed since it took a little while to get all those players.
