I asked awhile back but it never happened and I still stuck with them. They have no resource production value and serve only to take up room unless a planet is attacked.

If a planet is attacked a determined attacked is not going to be stopped by one item. You cannot possibly protect all your planets so its a better strategy to raise the resources of all of them so that losing one is not as big a burden.

Even if you tried, it would take at least 5 artifacts per planet to have any chance at stopping someone meaning you would lower production to the point of the planets being worth much less.

Those items are now scrappable.

What happen to reclaim artifact that you mentioned during early summer to reclaim artifacts so can apply to new planets?

id like to know this too, because unless the wiki is mistaken i can't get interrogation chambers past 200. and id like to move the few that i do have over to some better planets.

a reclaim structures feature would save me a lot of heartache for not figuring out sooner how good those structures are.
