Land Vehicles disappearing

Steps to reproduce:

1) load any land vehicle, move it around the mapaway from craft spawn locations
2) save game
3) Load a different vehiclea and click launch
4) Repeat 1-3 if bug cannot be reproduced (for me it happens first try). The vehicles will disappear even after saving game.

Note: picture is another example of land vehicles randomly jumping up when trying to switch to vehicle or spawning
