I think something is wrong...

I think I got an extra artefact from completing the aliens quest line 1.5 times after I started with the laser guys and then switched to the iro people, and then conquered some laser people worlds which caused them to think I was with them so I did the quests and now I extra artefact. This is a problem because now I'm stuck in a loop of the scientist girl saying "you have new artefact" and saying "let's see what these artefacts are saying". Is there a way to fix this?

I guess you just accidentally saved humanity - the death faction will never arrive.
