It’s come to my attention that if you get 13 plutoniums and click on the blimp to get items to unlock Olivia, that it won’t actually get anything for her unless you click on the specific item you want above her head.
Example: (and this is what I did)…if you click the blimp, you’ll get nothing. The blimp will go back in time and reappear and that’s that.
What you should do: When you reach 13 plutonium, click on Olivia and the item you want and click “GO” then you should get that item.
As we all know, plutonium is rare so getting them is a long-winded chore so don’t make the same mistake I did as I have to now collect 65 plutonium now instead of 52 😦 grim
Also, I’ve read comments that also say if you collect more than 13 plutonium before sending the blimp out then you’ll lose out that way too.
Don’t get caught out!!
