Problem: The server crash when loading it says it's a problem with datapacks but happens only with this mod installed, also it says this:
"java.util.concurrent.ExecutionException: com.google.gson.JsonParseException: Error loading registry data: Not a tag id"

Version: Multiworld-Forge-1.4.jar

I attach here the log too
latest (3).log

1.4.1 for 1.18.2 has launched, and fixed this issue.

...and introduced whole new ones.

What do you mean with new ones?
