Open your "NuclearOption-missions" folder.

In there, you'll find the name of the mission you added. You will need to copy the name.

Once you've copied the name, go back to your main directory within file manager, and open your "DedicatedServerConfig.json" file.

In the file, replace "BuiltIn" with "User", and change the mission name to the name you copied.

Once you've made the changes, click "Save"
