I've had this happen twice now with this same trailer; I park it somewhere convenient and I come back after a night's sleep to find it gone walkabout off somewhere. I searched moving trailers and see some videos of them moving slightly, but this trailer also changes orientation. Is this a known bug? Are the zombies borrowing it in the night and not putting it back? Do I need to bring out the shotgun?
