I've made several different piston doors over the last few days and none of them are working properly. I'm 95% sure that I've wired them right and I even youtube'd a few just to be certain I didn't forget something. I even tried making the simplest of simple 2x2 vertical piston door and the pressure plates don't activate the redstone.I have the redstone flag active and the piston flag active for my res. Is there something I'm missing?Another flag? Or am I just forgetting how to use redstone?Thanks !
