ClientPlayerEntity does not exist on dedicated server, so check the side before using it.

Will be fixed in the next official update. In case you need it for server with custom client - you can join mod Discord and ping me, I'll send you a fixed version.

Should be fixed in c40fc1a

Download will be available on the curseforge when update will be fully finished.
