There seems to be a major issue with the RealFuels mod and RCS Build aid. Any tank without a basemass in its MFT node will after being saved and reloaded have the wrong wet mass reported from RCS Build aid. I haven't really found the correlation of the mass it reports. The issue lies with RCS Build aid. There are no errors in the log or anything like that just RCS build aid report wrong numbers. I hope this can be fixed as I wondered for so long why my perfectly balanced planed would have now suddenly have torque after being reloaded.

Steps rep to repro.

1. Build a new craft. I used mk1 pod.
2. Attach any tank without a basemass in the MFT cfg file for the part
3. Open UI an add any fuel to the tank. Must be above 0L
   4 Examine RCSBA reported masses in vessel mass window
4. Save and reload craft.
5. Repeat step 4.
   mech jeb and the engineer report get it right consistently just RCSBA getting strange numbers. Using latest releases of applicable mods.
