When I completed following, I chose to blow everything up with a nuclear bomb. Now I would like to complete the achievements in following, but when I try to load following, I am transferred to the slums. I also tried to load different following tasks, but instead I am transferred to the main plot tasks and I load in the normal company.

I wanted to delete the following save and start over for the same character, but when I delete following, the main company will be deleted too and I don't want that. I don't know what to do
I would be grateful for any help
