i been doin this since experimental first came out... never had a problem
Well it seems this update has messed up the building placements and I thought I should tell everyone that when a player is sleeping you can place a twig Foundation on top of him, and I am pretty sure you can also put some hidden stashes/small crates but not the large boxs, once the Twig Foundation is on top of the player that is Asleep you can upgrade the foundation to something solid on the outside, like stone, sheet metal, or armored.
This is an easy way to hide your friends body, you can even have an alt and put all your items on the alt and log off.
