One of my buried crates randomly resurfaced. I believe it was after a server restart. But the crate had been buried and dug up and reburied an hour before the restart. It contained several pistols, random magazines, a skorpion, some seeds food, batteries a hunting rifle scope and maybe other misc. I have several crates buried around the area and non of the others seam to have washed out of the ground. It was in a field with thick brush. There were a couple u-70's on the surface and they were there also , but a fishing pole despawned. That's about all I can tell yah.
Nothing was taken that I could tell. It was just sitting there pretty much where I buried it.
