I have downloaded the latest version, as well as the expansion and I am missing the following parts:
SSTU-SC-TANK-MFT-A
SSTU-SC-GEN-ISDC

I have found the tank named SSTU-TANK-MFT-A in the menu, but there is no sc in front of it, which is why it is unable to locate this tank. Is there a known fix to this?

mine is also missing parts but its most of the parts :(
