Nwaneri future star academy

I can see plenty of others have made this mistake too but thought I'd start my own post in the hopes of getting some help off EA.

So, you've probably guessed I've apparently ruined my Nwaneri Evo. I used the normal evos up to 88 rated, decided to use the Evo for shadow striker ++ and now I can't use him in the new FS evos. 

EA need to implement a way to reverse EVOs, there's a reason there's thousands in the same boat as me, it was exactly crystal clear that you couldn't....I assumed aslong as I wasn't affecting his stats or rating I would be fine
