Suggestion: Make crates minable and placable
Suggestion: Enable the user to remove and place the crates (crates! not containers, see image).
Leave them uncraftable. This would make them a collectible. I think that would be a great addition to the game. It also makes the green dots on the map disappear, making sure that one wont try to go there again to empty and already emptied crate. I imagine this might be especialy useful in multi-player.
Players could hunt and collect them. It would be purely for bragging rights.
