Title: Crafting menu no longer sees backpack items after November 2026 Rust update (hidden slots ignored by client)

Versions:
- Item Retriever 0.7.9
- Backpacks 3.17.10
- Oxide.Rust [din version]
- Rust: November 2026 update (after the forced wipe)

Problem:
Players cannot craft using items stored in their backpack, even with Retrieve enabled on that page. In the crafting menu (Q), the items show as greyed out, as if the player doesn't have the resources. It worked before the November update. Moving the items into the main inventory makes crafting work again.

What I verified with a small debug plugin:
- Server side works: with 0 wood in inventory and 24,418 wood in the backpack, player.inventory.GetAmount() returns 24418, and so does API_SumPlayerItems.
- OnInventoryNetworkUpdate still fires.
- ItemRetriever still adds the hidden items to the outgoing main container message. A captured message showed: slots=51, items=29, 27 items in slots 24-50, while containerMain.capacity on the server is 24.

So the hidden slots reach the network message, but the updated client seems to ignore anything past the 24 real main-inventory slots when it checks whether a craft is possible. It looks like a client-side change in the November update broke the hidden-slots approach.

No errors or warnings from Item Retriever or Backpacks in the console.

It's working fine for me on latest client and server.

We cant craft items when we have it in the backpack

Ah sorry, it was not enough to reload plugin, server had to reboot too
