Then messing around thith a droper related redstone thing I stumbled across thins bug. We had two dropers to one we had a comparetor pointing directly in to it. When the comparetor got powered the item did not move and the both of the hopers read trigerd=True. when powering droper nr 2 it moved. Then having a powered redstone dust 2 above and one to the side of the droper it moved the item. even if the droper read: triggered=false. then placing a redstone toarth above droper 2 the item in it did not move to droper one, but a item moved from number one to 2. I found this realy wierd and that it was not intentional. The droper shuld not be powered by the redstone torch or the dust in the other example
