Minecraft Username: Gluupor Brief Description: Hoppers take 4 items at once instead of one item at a time. while this doesnt really affect hopper clocks it largely affects sorting systems. hoppers behaving weird started after the adding of the redstone clock preventer. Instructions: Build an item sorter as outlined here: https://minecraft.gamepedia.com/Tutorials/Hopper#Item_sorter How many times did you recreate this?: 3-4 times on my obsidian generator which has a sorter attached that is supposed to sort out the empty buckets Result: sorts out empty buckets and because hopper timing is off it starts pulling out lava buckets which eventually breaks the whole system and it continues to suck out lava buckets til there are none or the receiving chest is full Expected Result: the item sorter to only sort out the given item (in this case a single empty bucket after a cycle of obsidian mining and lava replacing) Evidence: come visit me @ /is warp gluupor since a screenshot wouldnt show much.
