fatally missing registry entries

Make sure you have the same collection of mods installed on client and server.

Share your client log:

1. open your minecraft installation path

(enter %appdata%/.minecraft in the file explorer )

2. open the logs folder

3. open the "latest" or "latest.log" file with a text editor

4. copy and paste the content of the file to https://mclo.gs/

5. send the link here

Double check if you have the same version of charm installed on both server and client.
