One truck was lost underwater and returned to original spawn.
Three other trucks were removed from their orignal spawn points for varying amounts of time: 3.5 hours, 3 hours, and 1 hour, (approximately).
All trucks returned to original spawn points in Msta, Staroye, Vybor and Lopatino.
All trucks were parked for more than 1/2 hour before server reset.
Will attempt to verify on different server.
