lol There is an option that says "You can recover the cape with your donation email." so I tried doing that. But either I have completely forgotten what donation email I used or the hacker had changed it somehow since it kept on saying that no donation has been made with that mail.
Hey gooal, I had the same issue for a long time. Me, being as stubborn as I am, just changed back the cape to my name every time this other person changed it back to their name. After like three months the guy stopped changing my cape to his account. Don't even bother mailing the optifine support, they won't help you.
I dont really care, but as I said before when I replied to KingTraitor, I can't remember what donation mail I used, so I can't change back to cape to my account
