Evo card disappeared

A similar thing happened to me just yesterday! I had a cornerstones evolved Rodri card which I was using to get full chemistry in my squad, but I got a second unevolved Rodri in a pack and ended up using that in an SBC. Similar to you it’s very clear the difference between a cornerstones evolved card and standard rare gold card so I know for certain I used the gold card and not the Evo and had no pop up about it being a player in my squad. However now it ended up taking my evolved player and showed up as a grey concept card in my squad and when I checked my cards only the unevolved Rodri was left. I reached out to support and haven’t heard back yet but I assume it’ll be the same boat as you where they can’t fix it which is frustrating since that card isn’t easily replaced (or probably replaceable at all)…a 90 rated Spanish cornerstones player to get me 33/33 chemistry. I probably will push for compensation but the frustrating part is they’ll probably just reimburse me for the Evo which won’t be enough to find a decent replacement for that card. It’s especially worrying because I use duplicates of evolved cards are pretty commonly in SBCs but now I’ll always be worried about it wrongly taking my evolved card which are not replaceable, some of which I’ve stacked multiple evos on to make that starting players. Hopefully they fix the bug and find a way to fairly compensate for having this problem but time will tell and I’m not very hopeful. Super disappointing though!
