0. ALWAYS PROVIDE INFORMATION ABOUT MODLOADER (Fabric / Forge) AND MOD VERSION (For Example 1.19.2-8.2.10)

1. Describe the bug
   Backpack does not have the icon in its GUI to equip/unequip it. I also can't equip with a hotkey or by shift-right clicking while the backpack is in my hand or placed as a block. I've looked at a previous report that was submitted and tried the possible fixes you suggested and they did not seem to resolve the issue. I do not believe I have any mod conflicts that would prevent equipping via hotkey and I do not have a backpack already equipped. Regardless of any mod conflicts, I'm not sure why the backpack would not have the equip/unequip icon in its GUI.

2. Write steps to reproduce the bug

3. What is expected behavior
   Expected behavior is to be able to equip/unequip the backpack by shift-right clicking while placed on the ground or by the icon in the GUI

4. Screenshots (If applicable)
   

It seems I was mistaken about being able to place it in my curious back slot. I did not realize I was trying to place it in the wrong slot. However, this still does not change the fact that it does not have the equip/unequip button in the GUI. Also, was the mod updated to where we can't wear the backpack at the same time as the Sophisticated Backpack?

If any mod that adds a back slot (such as Curios, Accessories, or Trinkets) is installed, Traveler's Backpack will automatically detect it and restrict the backpack to be placed only in the back slot. In this case, the equip button in the GUI will be hidden.

This change was made because many players were confused when they couldn't equip the backpack in the back slot while using such mods. Now, if one of these mods is present, Traveler's Backpack defaults to using the back slot for equipping.

However, this behavior can be changed via the config. To restore the equip button in the GUI regardless of whether these mods are present, set the backSlotIntegration option to false in the serverconfig.

if equip button is not present then you have to equip it in back slot from the mod that provides it. for example: curios, accessories, trinkets

if equip button is not present then you have to equip it in back slot from the mod that provides it. for example: curios, accessories, trinkets

It won't allow me to place it in the back slot

what version

Lemme get back to you on that; I'm currently at work.

Minecraft version 1.20.1. Mod version 9.1.36. Using Forge

What happens when you try to equip in back slot

Nothing. As I mentioned in my initial submission, It won't equip when I crouch right click while it's placed as a black and it won't let me place it in the curious back slot, either

That's strange, please join my discord and ping me when you will be able to test it in-game, we will investigate what is happening, I'd need some screenshots
