object space is a complete mess

Starfield has, what, 1000 planets, and each time you land the engine basically auto-generates a new approx. Skyrim-sized worldspace. The reference system has to have departed significantly from previous games for it to work. Even Skyrim was gently pushing the limits of how many objects can be referenced with the 8-digit refID (roughly 16 billion entries per .esp for all world objects, NPC-s, weapons, armor, outfits, consumables, spells, magic effects, markers, helpers etc etc since absolutely everything has to have a refID).

Of course Starfield is a mess coming from the simple refID scheme of the older games. The reference system in SF must be some sort of convoluted hierarchical system to be able to place probably hundreds of billions of objects over 1000 planets and retain persistency. It won't be easy to reverse engineer.
