Redstone Glitches

In the Debug World, if you use some of the redstone triggers(Specifically Levers and Pressure Plates[Stone is the only one I used]) They start copying themselves. Whenever the Lever is flicked, it sends out one or two. If a ladder is near by, it clones it as well. If you fly UP into a pressure plate, it spam clones them and crashes the game. This also happens with buttons.
