Loading and spawning Vessel in realtime from craft file...

[Pwolf]

Trying to load a craft file and then load it into the game. I can clone an existing vessel and spawn a new instance of it using something like:

ProtoVessel pv = new ProtoVessel(FlightGlobals.ActiveVessel);
pv.Load(HighLogic.CurrentGame.flightState);

However, if I try to load the craft file using something like:

Vessel tempv = new Vessel();
tempv.parts = ShipAssembly.loadShip("T:\\Programs\\SteamLibrary\\SteamApps\\common\\Kerbal Space Program\\Ships\\VAB\\Two-Stage Lander.craft");
tempv.orbit.Set(FlightGlobals.ActiveVessel.orbit);
tempv.orbit.epoch = tempv.orbit.epoch - .01;
ProtoVessel pv = new ProtoVessel(tempv);
pv.Load(HighLogic.CurrentGame.flightState);

I'm getting a reference object not set to an instance of blah blah runtime error. Did a little bit of troubleshooting last night to figure it out but I figured I'd come on here and see if anyone has done this before. Are there any mods out there that do something like this so I can reference the source?
