ive built a revolving lighthouse using redstone, it uses this design from youtube: http://www.youtube.com/watch?v=R-m3bj4t1jQ

This bug happens in both survival and creative, single player and multiplayer. The original design used a regular block on a sticky piston, either cobble or dirt, to complete the circuit when in use, and when turned off the sticky piston should retract with the block, breaking the circuit. When i replace the cobble/dirt with a redstone block, the idea is to have the whole thing light up and not rotate, because it lags the server i play on when on and rotating(also a vanilla server). When i try to break the circuit by retracting the piston via a switch, the piston will not retract until i break the redstone block. The attached pictures should help re-create the situation for you(sorry they are out of order, it should go 20, 27, 33,43,45 by filename). I tried re-creating the with just the base circuit of the entire design, but couldnt get the bug to happen again, its only happening when the entire device is built, which is why i included the youtube url. I hope you guys can fix this, please feel free to email me if im doing something wrong, missing something, or whatever at salomon3068@gmail.com. Thanks and have a great day!
