Describe the bug
i have last version of the mod for the 1.12.2 that is uploaded on curseforge (or at least the last one that appears in the app) in a mod pack with pixelmon and others, i had a normal traveler backpack on and then i created a dragon backpack when i killed it, and i pressed B to open my backpack to unequip, the backpack opens but the unequip button appears as the equip button and when i press it it says that i already have a backpack equiped

Screenshots

Required informations (please complete the following information):

• Mod version: TravelersBackpack-1.12.2-1.0.35.jar
• Mod Loader: Forge 14.23.5.2860

Additional context
maybe is an error with other mods but i could jsut go if you tell me in witch folder the equiped backpack info is to delete it, also it was on server, didnt test it on client

sorry 1.12.2 is not supported anymore, it's probably compat problem, you can try taking items from backpack, type /clear and make another one. Maybe that helps
