      Description

      An industrial furnace with a hopper sorting system is displaying different results between survival and creative. The same sorting system in creative works perfectly, however in survival, items travel through hoppers at an inconsistent speed 'skipping' one hopper when trying to distribute fuel evenly across the furnaces.

      Note that on initial construction of the sorting system, it worked, however after some more time played on the map the problem occurred. Any new fuel added to the input will now 'skip' the third furnace.

      I have copied the sorting system out of the survival game and in to a creative game using MCEdit, and the issue does not occur in the creative map with the exact same item layout.

      I believe this to be a game-size or map-size issue, or potentially a chunking or objects loaded in to memory issue. The creative map (where everything works) is 5.7mb, whereas the survival map (where it does not work) is 12.7mb. The system stopped working after exploring more of the map, creating a new building and herding some cattle.

      SPIN:
      Situation: An industrial furnace has two distribution systems; one for raw materials and one for fuel.
      Problem: The fuel distribution system is not spreading fuel evenly across 8 furnaces, more specifically, the third furnace is 'skipped' entirely.
      Implication: Only 7 of the furnaces get fuel, meaning that one furnace is never fired.
      Need: The hoppers must distribute items evenly and consistently across the board.

      Links:
      I'm adding these links through DropBox as one zip file is 12.7mb (too large to attach)

      Replication Steps:
      1) Add 8 coal to the 'Fuel' input on the industrial furnace.
      2) Wait 10-15 seconds.
      3) Inspect the contents of each furnace, the third furnace will have no fuel.

      Note that this is the same with any amount of fuel, divisible by 8 or not.
