Use the editor below to elaborate.

Please update the source code to 1.20.1 (which is the latest version this mod is using as of writing this) Since it probably has less bugs (which I assume.)

Additionally. I can try to port it to 1.20.4 or above versions if available.

Write a comment on this issue if so.
