If I could downvote this bug report, I would. Why on earth was this even an issue. You have directional redstone: redstone dust, repeaters and comparotors. And there in non directional redstone. Redstone blocks, levers, torches and buttons. Are you saying levers next to comparators should also interact? Ofcourse not.
Me and my girlfriend are playing from the same IP. Could that possibly have something to do with it?
