I ran a miner (at 9x9) probably a dozen times and never had the pump suck up liquids. I checked underground and saw the mining pipe just go through water.
Does the miner not need a pump anymore?
Also the info on the wiki for the advanced miner seems old, does it just do a 9x9 faster or is it 14x14 like I heard in a video? I also read that it needs no pump. Maybe all miners were changed like this?
