MC-74729Hopper priorities change
First off. It's been in the game since 1.5
Okay - If you want to divide items up using a hopper chain, lets say for a furnace array (see attachments).
This is entirely possible, in fact it works flawlessly... UNTIL you reload the chunks.
What before divided a stack in to 8 in 8 furnaces, now gives one furnace 15 items and the rest around 7 - making it useless!
You can temporarily fix this issue, but it will eventually reoccur
I believe it is caused by a change in the priority of the hoppers, but it is pretty hard to recreate so i could not get closer to the source.
You can check this video by 777static777 for further proof:

Hoppers stop processing items at a certain point when unpowered shortly, causing the items to build up.
Notice that this does not happen initially, but only after you relog or reload the chunks. (Same as MC-74729 which was fixed in 1.8)
This bug occurs up till an off-signal of 3 ticks. Which incidentally is (almost) equal to the speed hoppers process items.
Update: Whilst trying to work around this bug, I discovered more nonsense. I could create a seperate Issue altogether, but I believe the two are related and it might help fixing the Bug.
I tried to let the hoppers process 2 items at a time instead of one, but the result was just as irregular.
This time the items will arrange in a specific, but non linear pattern. (see "update" screenshot). This behaviour occurs with several different pulse lengths
Could also be related to MC-11193
I think I know what's happening. When the chunks turn into lazy chunks, for some reason the redstone stops updating but the hoppers still move items around.
Is this still an issue in the current Minecraft Snapshot 15w46a or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
I believe this issue was resolved as of 1.8.
I can't figure out how to change the versions affected on my phone and I currently don't have a computer
Done. Thanks.
