Launch the rocket using the crossfeed boosters. Notice that one of the boosters runs out a fuel a few seconds before the other.
@Kell This is something else. It's actually not a problem with fuel transfer. The craft is not symmetrical. Some other bug is at play in the designer that incorrectly calculates the fuel in the symmetric nose cone.
Wait I thought this was fixed
