i created a redstone elevator with standard redstone and pistons and though it would work, but when it the elevator reached the top it somehow got stuck.
when i looked at my redstone curcuits and noticed the middle row of torches didn't work. when i set the torches up in a way they didn't touch it worked again. also when i deactivated the first line of torches. the second row somehow worked again and the third row malfunctioned. when i reactivated the first line the second row malfunctioned again and the third row worked. if it is unclear what i mean tell me so i can upload a video explaining what happens.
