Great parts man especially the Command Module but I have noticed one thing. The HH-77 fuel tank seems to share fuel between tanks on the same stage. For instance if you build a rocket with 3 stock tanks & 1 stock LFR and then booster strap 2 HH-77's to it both with standard LFR's the fuel will drain from the first 2 stock tanks on the central booster before the HH-77 tanks start to be emptied. However the fuel will only move in 1 direction from the stock tanks in the centre outwards into the HH-77's and not back into the central booster. This has the effect of depleting the central boosters fuel before the strap on boosters and means you have to carry dead tanks for 1/4 of the first stage. You can get around it partial by doing an ATLAS and dropping engine but your still hauling a lot of dead weight. Is this the way the tanks are meantto work ?
