Hi,I've an item sorter using the design visible here: https://i.imgur.com/5E9kq9S.png . The hopper in front of the comparator holds a single copy of the item in its last slot, and the rest is filled with the appropriate amount of netherrack blocks.Everything works well at first. But then at random times, the sorter breaks. The single item and/or the netherrack blocks all fall down into the chest, and as a result, any other item passing by also falls into that chest.This behavior looks like a hopper timing bug - it suspiciously looks exactly like what many players reported with Spigot in relation to bugs 333 and 111 (https://hub.spigotmc.org/jira/browse/SPIGOT-111 andhttps://hub.spigotmc.org/jira/browse/SPIGOT-333). This was supposedly solved in Spigot 1.8.3, though, so I'm somewhat puzzled.Is the sorter design I use flawed, and if so, how? If not, is that indeed a server bug? Anyone else encountered that erratic behavior and found a solution/workaround for it?
