With a chest minecart unloading into a vertical line of hoppers, an item passes through the hopper connected to a comparitor for what seems like 0-1 ticks - it barely even flashes in the inventory when viewing the hopper's contents. The comparitor does NOT light up unless the item is in the hopper for a longer time (e.g. pausing/locking the hopper)
Tldr the comparitor doesn't output signal when an item is in hopper for very small amount of time.
The weird thing is, when this was built it worked fine. I assume at some point the chunk was unloaded and when reloaded it was broken. Destroying the comparitor and replacing it does fix the issue. The root cause may be the item being in hopper for too short duration, it seems far too short for normal hopper behavior.
This bug still exists in 1.14.4 (vanilla)
I have reproduction in my minecraft server.
