When both Kibe and the Stacker mod are installed and the max stack size is over 64, items are deleted when a player shift left-clicks a max stack into an entangled chest. To reproduce:

1. Install both Kibe and Stacker (https://modrinth.com/mod/stacker)
2. Change Stacker's configuration so that the max stack size is 256
3. Shift-left-click a stack of 256 cobblestone into any entangled chest
4. The stack has now become 64, so most of the cobblestone is permanently gone

This seems to be an inconsistent reproduction method. A better way to demonstrate the bug is installing Stacker and the Modern Dynamics mod or any other mod that adds item pipes, then attempt to transfer a stack of 256 into an Entangled Chest. Only 64 of the items are left while the rest are deleted.

It might also be related to North to South or East to West orientation for some reason.

Strange, it seems to have a 50% chance to start happening when I load up the game.

On a side note, thanks for your work on this mod! It has so many items that I use in all my modded worlds. I play with a large modpack (All of Fabric 5), and I use a max stack size of 256 with all of them. The only 2 mods that have issues handling this max stack size are Kibe and Tech Reborn. Item pipes and vanilla hoppers also delete items when inserting into an Entangled Chest.

This bug also occurs on 1.18.2 with stacker mod and is reproducible when you set the max stack size to any value above 64, not only 256
Still waiting for a fix ...
