I was looking at the protondb for Battlefield V and it has a gold medal despite the fact that it has been literally unplayable (the game won't even start) fpr 6 months now.

Are medals impossible to lose? Or do they run on some sort of manual verification? Is there some way to request a game to have it's grade changed.

For reference, the change in this case was the addition of EA Anti-cheat, which breaks linux compatibility and borked a considerable number of games, even older ones.
