Havent played in years. Been playing a week or so and I feel like upgrading more things in my ship. I had modified things before, but now since the engineers changed, it says I need to change to the new way but I cant and the dweller says to come back with new blueprints. How can I get blue prints if I cant make any? Do I have to delete all my previous modifications and start over? Fk all that. Grinding for engineers sucks. Of course if I show up there with a new ship, there is no problem. How do I convert my original modifications to the new way, or make a new blueprint??
