Mule Manager

Hey, For a long time when I used to play realm I would use a Mule manager I think it was the CL one. But no matter how hard I try I can't get an updated version of krelay to work, or maybe it's the plugin. I'm not sure but if anyone has a working version or knows how to fix it I would appreciate it so much, most of my stuff is locked behind a bunch of mules

i need it too
