Bug: Trying to finalize build with Trajectories installed causes vessel load to fail

[SprocketCreations]

When I click finalize build, nothing appears to happen, but if I'm in orbit the camera gets left behind; and the console is flooded with errors. It even crashed during one test.

I very much doubt this has anything to do with KIS (I do most of my testing with KIS installed), far more likely to be Trajectories as it would want the current vessel position. However, I am currently working on a fix for the orbit driver issue that causes the vessel to be deleted, which I think is the cause of those NREs.

I must have been really tired when I was doing the testing to have failed to notice that I had trajectories installed. Yeah, it was the problem. Should I update the bug report?

[taniwha]

It will help, I think. BTW, I've got the basics of the fix working, I just need to polish it up.
