I have noticed that in many instances, hoppers will pass their items into a chest of another hopper rather than allow the hopper below them to pull it (which should be the vanilla behaviour)

My idea is that despite hoppers checking for item from above at every tick, and hoppers only push items at every 8th tick, there are moments, when a hopper receives an item right at the moment right at that 8th tick its about to push items, and the hopper above doesn't have time pull the item out.

I run a really small server for close friends, we don't need to save calculation power on hoppers.

I tried to disable the custom hopper behaviour on spigot, but I learned that the previous fix (
setting "hopper-alt-ticking: true") was removed since 1.8.2.

There should be a solution to either, have hoppers item pulling action priority over hoppers transferring items, or a simple way to disable any Spigot change to hoppers all-together.
