Dear developers!
I found a bug or glich. If you type this into the console in F12, you will get all the badges !: The code itself is https://discord.gg/KpgGXrJ on this server.
I found it here: https://youtu.be/wnmU7uPaBo8. I used it and it works, so please take all the badges off me! Shadow King # 7171! Please fix it!
