Compatibility issue with TIS carpet "/carpet largeBarrel true"
to do:

1. "/carpet largeBarrel true"
2. put a large barrel and a hopper like inside picture

3. put many item into hopper
4. break the the barrel connected with hopper

then the hopper is pushing item into void.
How to temporarily avoid:
mixin.util.inventory_change_listening=false
the hopper optimism is still true
