Describe the bug
I made an automatic tree farm with Create, with a backpack to collect the items, and the items displayed are not the same depending on whether the bag is moving or not. It's just a visual bug, because when the machine stops, the items are back in the bag.

To Reproduce
Steps to reproduce the behavior:

1. Attach the bag to a moving structure (With Create)
2. Activate the machine
3. Look in the bag while the machine is running

Expected behavior
See the same items as when the bag is not moving

Screenshots

Versions
Minecraft: 1.20.1
Forge: 47.2.0

This is create "issue" or rather that create just converts whatever inventory is attached to it to create's interpretation of that inventory. For this to work as you expect would require an addition of compatibility layer in create that I could then implement compatbility for on SB side. I may try to approach create about that anyway, but this really isn't a bug on my side so closing.
