Your Expectation

Force manual backup with /backup start, remove item from backpack, restore backup, load into backup, item is missing from inventory and is in backpack

The Reality

The item is neither in the inventory nor the backpack, with the backpack state not having changed with the restoration
Global restore does not work either

This also works if you die then restore a backup, the backpack will be missing after restoring

Your Proposal

Ensure backup restorations always restore backpack state from the ModdedNetwork mod

Final Checklist

• I have searched this issue tracker and there is nothing similar already. Posting on a closed issue saying the bug still exists will prompt us to investigate and reopen it once we confirm your report.
• I can reproduce this problem consistently by follow the exact steps I described above, or this does not need reproducing, e.g. recipe loophole.
• I have asked other people and they confirm they also have this problem by follow the exact steps I described above, or this does not need reproducing, e.g. recipe loophole.

I confirm that it is already present in 2.7.4. Even with an automatic backup.

It can also duplicate items. If, at the moment of the backup, the item is in the player’s inventory, and then before the restore the item is placed in the backpack, after the restore the item will be back in the inventory but it will also remain in the backpack.

The backpacks are saved during backups. They are stored in the backpacks folder in the world save dir. The problem is that if you keep the game running while restoring the backup and reenter the world, the mod doesn't reload the backpack files.

If you you restart the game when restoring from backup (before entering the restored save again), you get the old backpack inventory as expected.

I'm guessing this is caused by GTNewHorizons/Minecraft-Backpack-Mod#12
