By @kogakumichi Positives Can unload up to 4 boxes at hopper speed simultaneously If every unloader is occupied and there are still boxes that need to be unloaded, the rejected box will cycle back into the small bulk, boxes will never despawn (according to my survival test). Can handle loose items and unstackables, though it does slow down the system. Negatives There's a very small chance that an unloader can accidentally throw the emptied box into the wrong water stream. This doesn't break the system per se, it only jams the mixed box loader. Notes When using the schematic, be sure to pay attention to any containers that might need to be filled with boxes in the box loaders or items in the hopper clock. This can be chunk aligned, don't build the red glass outline as that's for reference. There's no chunk loading system, if you want to chunkload, build your chunkloader inside the red chunk. I cannot guarantee that it works on other kind of servers but fabric servers. I think that's all that I have to add
