Okay, I just grabbed the Kethane mod tonight, and I landed 2 drilling rigs onto a deposit, which when I was done drilling, the scouter said it had about 20,000 units of kethane left. I go back to KSC, send a bigger drilling rig, and suddenly there is nothing there. I know I didn't mine it dry, it just disappeared, and the drills no longer collect any kethane. Any ideas why? E: my orbital scanner's orbit just passed through another previously detected zone, with no hits as well. It seems like my kethane has dissapeared from my kethane mod.
