0. Fabric 1.20.1 with TB 9.1.9

1. Describe the bug
   When using shift + left click with various items to move them from inventory to the backpack, and then closing the backpack and opening again, the items that were stored are now gone

2. Write steps to reproduce the bug

• Open backpack
• Use left click + shift
• close Backpack
• Open Again
• items gone

3. What is expected behaviour

For the tiems to still be there

After testing it, only the first items is stored

Do you play on server?

I had the same issue, it seems to be caused by the last Trinkets mod update.
So, at least in my case (MC 1.20.1), items disappeared when using the backpack placed on the back trinket slot. Wasn't an issue with Trinkets 3.7.1.

Shoot, then the fix might be there and not here
Sad

Also not playing online, just single player

this issue will be fixed in upcoming update for fabric

I can't reproduce the issue

All my items are saved correctly, what fabric version do you use

Can confirm this issue on my end. Using quilt loader 0.24 for MC version 1.20.1

Also, reverting to trinkets version 3.7.1 (instead of 3.7.2) does fix the issue. So not sure if this is an issue with trinkets or if its something this mod has to update for the new version of trinkets.

Fixed for Fabric

I just lost all my items to this same bug.
I joined my world and opened it to find that the crafting grid had changed and all my items deleted.
I really enjoyed that world, but since all my items are gone there is no reason for me to play it anymore.
