Describe the bug

To prevent crashes, I've found that using CustomSkinLoader version 14.17 works best. I'm not sure what went wrong with the newer version or what's causing the crashes. I've disabled all my mods and attempted to use the latest version of CustomSkinLoader on its own, but it still crashes.

Steps to reproduce

1. Open Feather Client and visit play.jartexnetwork.com with CustomSkinLoader mod and Optifine
2. If you don't have an account, make one. Then enter Bedwars and log out (only if you're new to the server)
3. Rejoin the server and you'll be instantly teleported to Bedwars and then you would crash afterwards
