Hi, so i have had this problem since starting.
when i work on the till, my car will flip over outside. if i am in the store for a few hours, it is normally outside but upside down. if i am in the store all day, it will be gone.
i have only had this happen when working on the till in any of my shops.
i have had 2 cars, and both of them, no matter where they are on the map, will flip over.
before the last update, if my car was gone, i could save and re load, and the car would be there, but since beta 6, i have to load the previous save.
the only thing i can see is that my parked car obstructs an NPC car that then flips it out, and eventually de spawns.
i have used a few choice words at this bug, but have just stoped working on the till now. lol
