Bug Description: As I said any vehicles of players sometimes teleport to random locations sometimes it's underground sometimes just another place on ground and sometimes it could be inside the buildings.
it's very hard to find the vehicles and only compass on top could help to find it.
the bug very common i see more and more people counter with this bug in internet, this bug could happen 1 times in 3 hours and sometimes 3 times in 1 hour of real time.
some "things" that we guess:
1)sometimes it teleport to the same possition if car stayed almost in the same place when teleported, maybe there is a problem of coordinates of vehicles when they "seeing again"? like it spawn back vehicles but see some trouble in coordination and teleport them to "default" coordination of chunk?
2)it always teleport in near location i think around 1 chunk, i don't know the actually chunk size in this game but never seeing teleport more than 100-200 meters(sometimes it teleport like a few steps but underground or in building).
but about the real reason of bug we don't have any idea it's just happening.
*once it happen to my friend on his eyes the car just teleported to another location, but he have a weak computer and play on very low settings
Detailed steps to reproduce the bug:
it's very hard to have an ordered steps to reproduce.
but for example.. it could happen if...
1)put 2 vehicles 1 for each player somewhere near in city.(like on road near any building like motel or house).
2)go travel somewhere, better for both players to move outside of line of sight to vehicles.
2a)or better option that one of players will be in helicopter make some circle around map(to another city) and second player wouldn't be near vehicles.
3)after a few minutes return and try to find your vehicles.
Actual result: the vehicles teleport to another possition and sometimes it's hard to find them or need to dig them.
Expected result: vehicles MUST stay in the place where players put them and don't move/teleport by themself.
sorry didn't make screenshotes because didn't think i would make report 
but after many of times bug repeat decited to make report, when i will play again with friend and find faced in this bug we will make screenshot, and will try to add it.
