Overflow Hopper Fix

Copper Hopper Overflow Fix is a small unofficial Fabric addon for the Copper Hopper mod.

It improves the behavior of stacked Copper Hoppers in vertical storage systems. Normally, when the chest connected to a lower Copper Hopper is full, items can get stuck inside the hopper buffer before the next available chest is filled. This addon changes that behavior so items can continue through the Copper Hopper stack and move to the next available hopper and chest instead.

This is especially useful for filtered storage systems where multiple chests are stacked vertically for the same item type, such as stone, cobblestone, dirt, wood, or other bulk storage items.

The mod only affects Copper Hoppers and is designed to keep normal vanilla hopper behavior unchanged.
