Describe the bug
Dropping the backpack as an item to float in the world crashes the game.
No other mods added; only SophisticatedBackpacks and its relevant Core Mod.

To Reproduce
Steps to reproduce the behavior:

1. Obtain Backpack
2. Drop Backpack or Die
3. Not Stonks

Expected behavior
I expect the item to be droppable in the world as is.

Versions
sophisticatedbackpacks-1.19-3.17.12.626.jar
sophisticatedcore-1.19-0.3.9.63.jar

Forge Versions: 41.0.96 and 41.0.98

Going into third person also seems to crash the game.

Adding to this, with https://pastebin.com/m8KcS1JR crash report from a completely clean install, with only core and backpacks installed. Was in creative, put an empty back pack in my tool bar then dropped it.

Adding onto this again, going into third-person with the backpack in the main hand or the offhand causes a crash.

this is fixed in the latest version on curseforge
