I were trying to make a piston door with a light sensor (im not so good with redstone) and i were testing it by placing and removing a redstone wire. It's day. Start position = good Place the wire = It activates correctly.
REMOVE THE WIRE = Part of the circuit doesn't deactivate.
Is it my faulty redstone? Or a bug?
Same mistake as MC-746. Always try to read up on the wiki first, before submitting a bug.
