Recycle server ground cleanup materials

In Survivor mode, when the server does ground cleanup, it seems to remove the items from play permanently. In a long-running game, this can results in severe scarcity of raw materials late in the game. Specifically, the
(amount of unfound stuff remaining through natural gameplay) = (total unfound stuff at start) - (stuff in placed blocks + stuff stored in chests).
Late in the game, this subtracts two big numbers, giving a small positive number.
A server with an aggressive ground cleanup policy (to reduce lag), will significantly reduce unfound stuff by quickly removing it from play each time someone is killed. So then
(net amount of unfound stuff) = (amount of unfound stuff remaining through natural gameplay) - (total stuff removed by server due to ground cleanup since start of game)
The (total stuff removed by server due to ground cleanup) is a summation of stuff removed across time, so that quantity will grow as the game progresses. For a hyperactive cleanup policy and a lot of inexperienced players, the dynamic may be that they get killed often, resulting in over 90% of the stuff the collect that is not yet placed or secured in a chest being permanently. That dynamic can result in extreme scarcity late in the game, to the point where gameplay gets seriously distorted due to the extreme scarcity.
A fix is to recycle the equivalent raw materials into randomly selected unexplored locations.
