Searched the forums, couldn't find anything quite like the issue I'm having.
Playing on an SMP server. The standalone pump works fine with water; fills cells and pops 'em out. But when I try using the pump with the miner, the pump fills and then nothing happens. I stick the empty cells in the top slot and the pump just stays filled while the cells sit there. I remove the pump, replace it, then the miner is able to continue mining down but I lose the lava/water that was being stored in the pump. Suggestions?
