When trying to build a temporary stash in a lake, My crates and other items Won't sink to the bottom and float on top. However if you throw items they will sink to the bottom. I have only checked this on 1 lake so far.

Load into dayz Xbox Livonia

Travel to a small late at coordinates X: 0.78 , Y: 0.46

Drop Items into lake by dragging them on the ground or dropping them (No thowing)

Problem should be recreated

Item drops and sinks in the lake becoming hidden by view. Still should be accessible by being on top of it.
