I am playing with 3 other players on our private Server, but our base is miles away, so the Quarry can't mine something from our machines.
I searched a bit in the mining area and found a ravine with some random placed Wooden Irrigation Channels. The other thing that was weird. When I first entered the Extreme Hills I found 6 Redstone Comperators randomly placed on the floor. When I attempted them 3 of them dropped. Something weird is going on there xD
