Backpack Disappeared after Crash

[cymophic]

Describe the bug

After dying with my linked backpack equipped in my survival server, I crash.
Then upon checking shelf, the backpack is missing, making me lose all the stuff I had.

I was then able to reproduce it multiple times in a test world.

To Reproduce

1. Have the Backpacked mod with my modpacks.
2. Crash after dying, had a fairly high chance when I tried replicating it in the nether.
3. Reopen minecraft world and check shelf.

Expected behavior

I should have my backpack in the shelf it's linked.
