I think the little quantum campsites are despawning after a certain amount? I came back into the game, and where I had put my lights they were gone (light still there, but the campsite is gone). Maybe I've simply explored so much of the map that there can only be a certain amount of those campsites at a time? No clue when this started happening, but I think I'm gonna avoid exploring too far for now, just to be safe. Collecting resources is satisfying enough, as is.
