no alien artefacts

[martinuzz (OP)]

So, I discovered some ruins. My Xenoarcheology team identified it, and my engineers have fully exploited it.
I terraformed the planet it was on, and have a starting colony of almost 10m population there now.
However, in the wealth tab, the planet is not producing any alien artefacts for trade.

I thought that colonies on a planet / moon with ruins site produced alien artefacts?

I have this in my current 4.91 game also. Colonies don't start producing all of their commodities until  20 million pop (maybe 10, I forget which and I'm on the wrong computer to check). I'm assuming for the moment that this is why.

[martinuzz (OP)]

Aha. I didn't know that. That would make sense. I abandoned that game cause I got kicked to the stone age by some unfriendly aliens, so I can't test it there.
My new game has a fledgling colony on Mars though, with ruins. With population 0.24m, it only has one trade good, infrastructure.

Testing in progress..

At population 10 million, the population of Mars now starts to demand alien artefacts, instead of produce them.
However, the number for current import requirement is listed in parenthesis, instead of normally.

[martinuzz (OP)]

At population 324 million, the colony still does not produce alien artefacts. The numbers indicating current import requirement are no longer in parenthesis.

Only colonies with ruins produce alien artifacts.  Once ruins are fully exploited, they disappear.  Thus, your colony does not produce alien artifacts because it does not have ruins (anymore).  I suggest posting your problem in the bugs thread.

Ah. The ruins on Mars have been fully exploited by my engineers, didn't know that caused the ruins to disappear. That explains it then.
Guess I have to find some ruins on a planet, and don't touch them with engineers to get some alien artefact trade going, then.

Or only touch them a little.^^

Using the search button I found this post, and I have the same problem as the person who asked first.  The only difference it's that i haven't fully exploited the ruins.  They are all intact (but i have identified them with my xeno archeologists).  Why the colony (92M) doesn't produce artifacts?

[Yonder]

I'm guessing it's a bug all around then. Even after your government teams have swept the ruins of everything of industrial, scientific, or military value there should be plenty of alien teddy bears, alien toothbrushes, alien sports paraphernalia, and other items to export.

[Faber81]

So artifacts are bugged then? Even if you don't exploy the ruins with engineers nothing can be done, right?

[TheDeadlyShoe]

Apparently.  I recall reading that theyre still supposed to produce artifacts even after being exploited.

[Thiosk]

Im pretty sure I put up a bug report about this too, some weeks ago, running the newer versions 5.53 or so.

Parentheses around the artifacts numbers, none produced, unexplored ruins on the planet.

I see. . .  Thanks for the answers everyone

Wait you are sure that you have ruins on Mars? Iirc the standart sol has no ruins at all.
