I have a biig problem. I've built an 3 by 3 piston door on Minecraft Win10 with MumboJumbos help. It is working really great with a lever. But I don't wanna go down to the mechanics to open the door, so I put a repeater to the block with the lever and removed the lever. After that the Piston Door doesn't work anymore. I also tried it with torches under the block. Sometimes it works for a couple openings, but then it fails again. After I put the lever back on it works perfectly again. Any Ideas to fix it?
Thank you very much.
PS: I did the Screenshot with my tablet. It was easier and the World is on a realm so I can enter it from everywhere.
