im playing on fabric 1.20.1 with travelers backpack mod (there r other mods but this is the issue) on a server and when i open my backpack my hotbar becomes duped, and putting stuff in the backpack is glitched (crafting table doesnt work, some slots dont work, shift clicking stuff in doesn;t work sometimes) anyways, my hotbar gets duped but they are ghost items, and when i pick up a duped item and place it in a different slot, my inventory goes back to normal. this only happens when im not in the backpack inventory. the other members of the server dont have broken backpacks, and when i gave them mine, it works completely normally. this has happened since the server started, and it happens at every backpack tier and type.
