i am having an issue where my redstone engines wont pump at all, no matter how i try and power them or what i connect them to UNLESS i put 2 directly next to eachother. it just started happening on my server however they worked before that when i was using the same build. also my mining turtles show black screens. does anyone know whats going on?
