I tried to add Methalox to the list with a patch.

LqdMethane (CRP resource)
Oxidizer

The FuelType will not show up in the MFT-A despite being added, and the LqdMethane resource will not show up in the volumecontainer list.

`
SSTU_RESOURCEVOLUME
{
name = LqdMethane
volume = 1.0
}

SSTU_FUELTYPE
{
name = Methalox
RESOURCE
{
resource = LqdMethane
ratio = 10
}
RESOURCE
{
resource = Oxidizer
ratio = 1
}
}

@part[SSTU-TANK-MFT-A|SSTU-TANK-MFT-R|SSTU-TANK-MFT-LV|SSTU-TANK-MUS|SSTU-TANK-MFT-D]:AFTER[SSTU]
{
@module[SSTUVolumeContainer]
{
@container,0
{
resource = LqdMethane
}
}
}
