Describe the bug

Single player world:

There was no button to put on back when opening it from your hand, but you could drag it into the backpack trinket slot and then the hotkey worked.

Server world:

Green arrow button to put on back is shown, and the backpack can't be placed in the trinket slot anymore.
Pressing the green arrow button will clear it from inventory but there's nothing in the trinket slot and the backpack hotkey doesn't work.

To Reproduce
Steps to reproduce the behavior:
Install [(https://www.curseforge.com/minecraft/modpacks/deathdusk)] on a server.
Join with client(also needs client version install).
Get a backpack
Open
Equip on back slot
-> Now the backpack is locked on back, the hotkey is not working and backpack disappears on death.

Expected behavior
The same behavior as described for Single player world.

Required informations (please complete the following information):

• Mod version: [1.18.2-7.1.0]
• Mod Loader: [Fabric]

Additional context
Personal suspicion of KubeJS scripts(i'm just a user, not the author) because it modifies the recipe, and it seems recipes that are modified this way don't show up in the right side recipe menu either.

Is trinketsIntegration config option in Travelers Backpack mod enabled both on server and client?

Sorry, 1.18.2 is still under moderator review you have to wait some more time. Don't know why does it take so long though

https://www.curseforge.com/minecraft/mc-mods/travelers-backpack-fabric/files should be fixed in latest versions

Is there a mistake maybe? I see the 3 versions updated but not the 1.18.2 one

This is what i get screenshot
