Describe the bug
It looks like the 9 upper slots of the interface are offered twice to LBA as a FixedItemInv. Set a full-block interface to keep 1 cobblestone block in store, connect it to a chest using MI item pipes. It will crash because simulation extracted 2 cobblestone blocks, but action only extracted 1.

Environment
Fabric 1.16
Happens on AOF3 and in dev env with only a few mods
