yea, the tank is enabled, i even went back and added fuel transfer pipes to the fuel tanks the RCS thrusters are on (never had to do that before but i figured why not give it a shot) the ship is the mechjeb pod, 1 adapter fuel tank, and 4 small fuel tanks (all stock) 4 poodle engines, i cant remember the name of the thrusters, 2 batteries, solar arrays, a heat sink and radiators (mod), and a docking port at the bottom since this is basically my delivery craft to land stuff on other planets with no atmosphere. http://i1251.photobucket.com/albums/hh546/crash1187/Untitled_zps3uczuqil.png' alt='Untitled_zps3uczuqil.png'> this set up (minus the extra tank under the mechjeb (i added it to see if the mechjeb would pull from it if it was attached directly to a mono tank, it didnt) worked fine before the update
