After I created a reverse input piston, I saw that there were some bugs with this. The first bug was that if I placed a redstone torch next to it or under it to power the piston it would go like normal and acrivate the piston. If i then gave this torch a redstone signal to turn this torch off the piston would stay in it's on position it woudn't retract. The piston still sees the redstone signal but woudn't update. The second bug is as you can see on the attachements, the piston still sees the redstone torch even when it's not connected or there's a block in between. This is found on the multiplayer side of minecraft, this isn't in singleplayer.
