I think my timelines save is bugged. Or i did something wrong.

So I sped through timelines. I loved the missions even though a few of them were tedious. I was mainly doing it for the free ships for my saves.

But then I noticed in my saves I was missing a few ships.

The dart and the experimental shuttle. But I completed timelines i think, still the mission won't start.

Did i mess something up do I need to do something.

I also never got the "white room" cut scene how do I fix this?

I have the Sapporo and odachi so I finished the missions.

If I load timelines I have no missions or anything. Any ideas?
