Sim can’t trade for Strangerville key card

My last save went wonky so I put my Sim’s 13 pieces of Strangerville evidence in her house and saved her and her lot to my library and then started a new save. I put the evidence in her new inventory and went to Strangerville but she couldn’t get evidence from the scientists or military personnel. The only option was to Talk About Strangerville. I could plant bugs so that’s how I got the last 2 pieces of evidence and compiled the dossier. But now I can’t do anything with it. I can’t trade it to the curio guy all options are grayed out and I can’t trade only talk about Strangerville. How do I complete this aspiration?
