@Morty044 do you have a video of this occurring if it's still an issue? Where are you trying to get it from? Do you have the 'reg' plate for it from your phone app?
Devs have had a look and cannot see the vehicle being blacklisted so no reason for it to disappear.
Excellent news! This has now been fixed by the development team and will be released in a future server update.
Thanks for doing your bit to help us keep the servers bug free!
