I went into the robostore and went up to collect the artifact. as i went up i collected some scrap and was attacked but polis robots. During the fight the table which the Kommonde 64 was on blew up making a hole in the floor. After the fight I looked for the artifact but it was gone. I tried to reload the save, but it saved at the end of the fight.
I tried to leave the area and come back. The table was fixed but the artifact was still gone.
this is the last one i need to get.
