Guys, I've encountered some strange behavior. Never used Kethane before, installed the 0.8.4, constructed a vessel with a large tank and a couple of small drills, landed in on Minmus in a spot that definitely has kethane (scanned by a satellite), when I start drilling, it shows green mist around the vessel, but the kethane tank remains empty. I tried putting the drills right on the tank, on another parts of vessel, tried to use large drills instead of small ones - no luck, there is green mist (as far as I understand that should indicate that kethane is being extracted), but the tank remains empty (oh and I checked, there is enough electricity generated on board). What could possibly be wrong?
