I don't know if this occurs to anyone else, but seems like it doesn't work for me. If someone can help me out, it would be highly appreciated. Every time I open up a world of any kind, multiplayer or single-player, it says, "Cape could not be set!" I was kind of confused and took everything else unnecessary from my mods folder. Every time I also clicked the capes GUI hotkey, it would immediately crash my server with a small command prompt with a little game/crash-report.
