------------------
1) Enter persitent universe
2) Call up Argo MPUV Tractor
3) Hover above ground with the MPUV T
4) Load up cargo boxes to the cargo grid
5) MPUV begins to descend to the ground once 14 scu are exceeded
6) MPUV can´t take off anymore unless you reduce cargo load to 11 scu or less

What happened
-------------
MPUV T still can´t stay in the air or lift off when loaded to its full 16 scu capacity. Craft falls to the ground once more than 14 scu are loaded onto it - cannot take off anymore unless cargo load is reduced to 11 scu or less.

What should have happened
-------------------------
MPUV T should be able to lift off and hover with its full 16 scu cargo capacity loaded.

Workaround
----------
MPUV T can only be used to full cargo capacity in areas with no gravity.
