Ok so, I was messing around with Redstone, then I tried to make a clock.
Then, I noticed that the Redstone was powered but the pistons were not, I relogged multiple times and also went into other worlds to try, same result. The only way I can fix it is if I get rid of the repeater, then place it back again, or from my first design I need to turn the Redstone back to the 1 dot Redstone then back to the 4 way Redstone and then it would power.
