So I run a small server using your mod. Several of my members have contacted me about an issue preventing them from joining
it says

"Registry remapping failed: Received ID map for minecraft:game_event contains IDs unknown to the receiver!
- twm:click
- twm:death

I've seen several people online with the issue but i never understood how they solved it and if its not already known it might be good to report,

Are you using the latest version and is the client doing so as well? If I remember correctly this but was caused by something on the server that wasn't processed correctly on the client side.
