Hi, I just tried your mod in my modpack and noticed the server crashes on startup.
I am using FML 36.2.8 with Minecraft 1.16.5 and Multiplayer-Server-Pause-1.16.5-Forge-1.0.0.

Here is the crashlog :

I am using Roadrunner, if it helps pinpoint the issue.

That's what I get for testing the mod on Fabric 😂

I'll have this fixed up and posted on CurseForge soon

Fixed versions are up on CurseForge. Thanks for the issue report!
