In my experience, if anything is dropped into the world that *isn't* marked as a 'deployable', and you enter/exit any seabase you built or your lifepod, the dropped items are intentionally despawned by the game. It might have something to do with keeping the game's memory from overloading? Not sure, I'm not a programmer, but any time I drop things like dead fish, pieces of copper/titanium/etc or plant samples, etc, etc, when I'm playing, this happens.
