So I've finally started playing this, but I initially loaded up a debug FRED and tested every ship to make sure it all loaded properly.  I get an error with the beam prototype model about not being able to load the sm-trans texture.  Oddly enough, it IS in the VP file.  Not sure what's causing that.  There also appears to be a missing texture asterod9 (yeah, I know it's not spelt right), which I eventually found in the Inferno Alliance VPs.  There's also a warning about docking normals with umb90.pof, which I don't understand either.  Finally, as I started the first mission, I ended up with no primary weapons.  Since there wasn't any combat in the first mission, it wasn't a problem and I thought that perhaps it was some kind of plot choice so you couldn't destroy anything, but then when I checked the loadout room in the 2nd mission, there were no primaries there either.  Would creating a new pilot help?
I also noticed a problem that I tracked back to the 3.8X Media VPs, so it's not a problem with SAH.  It seems that the new Leviathan wasn't included, but the tables for it were.  Fortunately, I had the model in my 2014 VP folder.
