What does this pull request do?

Gets rid of the guaranteed 4 items per node in exchange for the node despawning on a coin flip (mining, excavation, harvesting) or guaranteed (logging) after each successful obtain.

Do note that the relocation may effectively end up on the same position you just exhausted, but that was already the case.
