JJC NBT FIX
The author built this one for Minecraft 1.20.1 on Forge. On other versions it may install and then do nothing.
JJC NBT Fix fixes a common NBT error caused by JujutsuCraft.
This mod is mainly required on the client side and is recommended for anyone playing with JujutsuCraft. It can also be installed on the server side, which is optional but recommended for better stability in multiplayer environments.
The mod helps prevent issues caused by broken, invalid, or unexpected NBT data from JujutsuCraft entities, items, or player data. This can reduce errors, crashes, and other problems related to corrupted NBT data.
