You’re basically asking for the game to iterate through every single square of the reality bubble and if it does not have a roof, then iterate through every single item in that square and pick a random direction to move it.
Pros?
-Oh, that pile of junk I saw a few days ago is scattered away from where I last saw it. Neat.
Neutral
-Stuff you would have found randomly distributed before, is still randomly distributed.
Cons
-Oh God, here comes the daily lag spike! Brace for impact!
Probably not worth it for that kind of CPU load.
