My Founders Cape is disappeared

In update 1.16.200 there was this bug (or they fixed it in that version) that gave the Founders Cape to everyone, even players who hadn't redeemed it. I was one of the people who had legally redeemed it, only for them to take it away from me (probably by mistake). At first I thought it was a bug and so I didn't notice it, but now I want it back. Sadly I don't have any screenshots or videos but I'm honest. Please fix this bug.
