Kerbal Space Program

The Vessel category in the mission creator has tests for vessel mass, velocity and other things, but not part count. While it may seem like mass can be used to determine if you lost any parts along the way, the change in fuel results in a change in mass. I want to create a test to check that you did not lose any parts (destroyed or decoupled) from one point to another.

Note, the Vessel Mass node does not allow recording of the mass at one point to compare with the mass at another (but it should) so a new test may have to be coded to be able to compare a part count from one point to the part count in another as well, especially when the player designs their own ship so you can't be sure how many parts they will use to begin with.
