I have built a simple hopper/dropper "vending machine" as seen in the pictures below:
When an item goes into the hopper, it activates the comparator which then ignites the redstone torch. The torch then "short-circuits" itself after 8 ticks, causing 8 items to be dispensed. This works as expected in Minecraft 1.9 (Mac/PC edition), but does not function properly in Minecraft Xbox One CU41.
In Xbox One edition, the torch ignites (as expected) when an item is put in the hopper. However, it also ignites randomly every 15 seconds or so.
According to the Minecraft Wiki,
[The redstone torch] will re-activate when it receives a block update (an adjacent block changing its state) or a redstone update which wouldn't normally deactivate the redstone torch.
Neither of the circumstances for re-lighting were being triggered, as I left the device alone. Why is this happening (is this a glitch?) and how do I fix it?
