I was playing DayZ on Livionia official stable.
There is an anthill in the woods south west of Gieraltow. I placed the wooden crate on top of the anthill an buried it, hoping the pile of dirt will blend in on the anthill.
When the burying in animation finishes, the crate disappears but the pile of dirt is not visible. Probably because it is covered by the anthill.
It is then impossible to resurface the crafte, because I do not get the promt and cannot see the pile of dirt.
