Describe the bug

On the Aternos server (yes, I know) backpacks are unable to combine. Doesn't give end result when combining armour (example: gold) with any backpack. Combining another backpack with a combination backpack gives the usual leather armour....

Expected behavior

Combining normally

Note: I used Crafting Backpack for ss
