I looted a couple of bases back in March and I found that these players where able to place 10 barrels/crates or more in the same spot. Just take a look at this screenshots. The first picture shows approximately 10 barrels stacked inside of each other inside of a bathroom. It's a little bit hard to see because the screen shot was taken during night time in the game, but you can see the lip of the 10+ barrels stacked inside of each other looking like hula hoops. The second picture shows all of the barrels that I moved out of the bathroom into the next room to be destroyed. The third picture shows another base that I looted where there was more than 10+ wooden crates stacked inside of each other. This is very unrealistic, and it degrades the experience of the game to have to deal with this type of glitching and to know that we are playing with hackers to some type of degree.
