That vehicle doesn't exist. Is this from a log you're encountering this or did you run into this in the app? I've improved that error handling though in 1.0.10.

Hi it's from the logs, is this an issue with the migrator not moving the vehicle over or that the vehicle has been deleted by the user? If it's been deleted how is it being accessed to generate the error?

If it’s from the logs then it is someone accessing a wrong or outdated link. Happens all the time with links, especially on busy sites, just shouldn’t be logged as an error in the system log.
