I updated the mod on the server and client, now when I try to open the Baubley inventory, I just get kicked out of the game.

Server log:
https://pastebin.com/F1nB87gq

the same error occurs if you try to go to a server where your mod is not installed

pastebin is saying the link is private or waiting for a moderator, can you link it using https://mclo.gs instead?

fixed in v1.3.1, p.s. this mod is needed on both the server and client to work
