Mission builder fails with "Could not start mission" on certain craft built with Breaking Ground DLC
To reproduce:0. Create a new mission.
1. Place the attached KALYPSO.craft file in the mission's SPH.
2. Spawn the craft in the "Spawn vessel" node.
3. Launch the mission.
- Expected: Mission launches.
- Observed: Misson fails to launch with "Could not start mission" error.
Notes: The bug is reproducible with some other helicopters I've created. It also makes no difference if I attempt to launch it as a user-created craft by loading it in the SPH and the clicking "Launch" to start the mission. Other craft launch just fine so it's clear it's something about these that don't work. The craft are stock + DLC, no mods used.
