Description

In ServerLevelMixin you have 2 instance of check which assing a value to that PrimaryLevelData K field.
Obviously this allows for a branch in whih neither are true (which can and will happen with mods as that class is NOT sealed and mods are free to subclass it), causing a crash in the code that's right after that since you arent null checking it
