Yeah, I got that too, but only while harvesting Skylites. Curiously, there appeared to be seven of them ready to be picked up, but the extra three gave me that message, like they'd appeared before they'd actually spawned or something. I find it rather curious that there's an error message specifically included for that possibility, like it's a known bug (or a feature?)

Anyway, just try collecting them again later.
