[Mod Help] New Shuttle Mod for Save Our Ship 2 Debug help

[WolfoftheWest]

I'm making a new Shuttle for SOS2, but every time i try to launch the shuttle it removes all fuel, deletes the cargo/occupants, and throws this error

Root level exception in OnGUI(): System.InvalidCastException: Specified cast is not valid.

I'm assuming that its telling me that I'm missing an "arrival" def, but I haven't found one in Save Our Ship 2's files to use as a base, so I'm requesting help
