I belive that he meant a payload, and as we all know, payloads, when docked to, have unlimited fuel and O2 (Maybe
N2 as well? I do not know...).
Any way, to the problem at hand. I do not know what caused this problem, but I do know a solution... in theory. Ok,
get off you knees, and stop calling "messiah". James will do. The solution is this: Keep your airlock closed! Then simply
start a O2 transfer, from the payload to the DGIV. That should fix it. The transfer switches are the funny knobs (not
noobs!) under the O2 Display. You know, the thing with the blue bars.
