Points ladder

I have absolutely grinded the game since the day it was released. So much so, that I was able to use all my players and all my coins to get the Sergio Busquets card as an sbc, and get to level 39 on the seasonal xp ladder.  He was my second most expensive player, behind a first week Marcelo icon that I packed. However, when I reached level 39, I realised I earned a purple cosmetic reward ladder card.  And like the absolutely stupid person that I am, I put this card onto Busquets (the card was already decent btw) and it ruined his chemistry, and therefore, my whole teams chemistry. My expensive team, that took weeks of hard work, has now been ruined, because of one stupid mistake on my part. However, I do think that this is incredibly bad on EAs part too, that they would reward you with something that can have such a detrimental effect to your team. Yes, it was my mistake, and yes, it probably was written in small writing somewhere that it will ruin the chemistry. But come on EA, I bought the game to play the game, I don't load onto to FC to study everything that is written. I'm writing this, because as of now, I no longer play FC. In fact, it is getting uninstalled later tonight. Because, I have spent way too much money, time and energy on the game, for everything to ruined by one silly mistake. Before I uninstall, does anyone have any advice, or solutions for me, to get my Sergio Busquets back to its SBC original form? Thanks for reading, and have a nice day!
