Codex Rumored - were Xeno sites listed as rumored before being discovered?

[Oytis57]

I'd guess either something to do with how orbital positions of planets interact with the NSP placements, or one of the servers with NSP data is out of sync, since some of the ones around the Colonia nebula have disappeared and reappeared several times now.

Obviously if you only visit a Codex location once and see it's not there, you won't notice if it reappears again a week or a month later.

Other than that "flickering" they've all been pretty consistent in location since 3.3, though.

Whatever it is is a problem on "their" side, that's what i wanted to point out instead of weird theories about how that space lifeforms spawn/live/ die disappear By the way on my last trip to the Abyss I passed a couple of Codex sites on the way there and on the way back...nothing there both times.
