Describe the bug
Roughly every couple of ticks the console will spit out this error. ProtocalLib will also block any command from functioning including commands in the console.

To Reproduce
Steps to reproduce the behavior:

1. Start a Mohist-1.16.5-603 server
2. Add ProtocalLib and Create Mod
3. Join and move around. Error will occur in console

Expected behavior
A huge fatal error and all commands to stop functioning.

Additional context
This may just be a error because protocallib isn't compatible with Mohist so oh well.

Currently not planning on supporting mohist
