When using MrCrayfish’s Backpacked mod in conjunction with the accessorify integration (as part of the Better Minecraft 5 (NeoForge) modpack), we have encountered a consistent duplication issue related to gravestone recovery.

Steps to Reproduce:
1. Equip a backpack in the back accessory slot (via accessorify).
2. Die (e.g., via /kill or natural causes).
3. Retrieve the gravestone (from the Gravestones mod).
4. Player receives two backpacks, both containing identical items.

Expected Behavior:
Only one backpack should be returned with its original contents.

Actual Behavior:
Two backpacks are restored to the player—one likely from the accessorify slot and another from the gravestone’s inventory restoration—causing an item duplication exploit.

Additional Notes:
The backpack is equipped in the accessories slot but upon retrieving the gravestone it is not put back in the same accessories slot rather it is moved to an empty inventory slot

Modpack:
Better Minecraft 5 (NeoForge Edition) Version 27.5
Minecraft Version: 1.21.1
Backpacked Version: 3
You’re in Grave Danger Version: 2.0.11
Accessorify Version: 1.3.5

Can confirm this we got the same issue right now, thought its an accessories issue first so here is the bug report i made there, no point in making another one here now i guess, contains the logs if they are of any use wisp-forest/accessories#279

I had the same problem, which is (temporarily?) solved by setting keepOnDeath = true in config/backpacked.server.toml
