Coventant didn't previously had a diplomatic roleplay that was possible.
With this you can resolve this questline an no one has to die.

Put the covfix.esp in your fallout4/data folder. It might be hidden under the steam/steamapps directory.
Then put the QF_MS17_00022A08 file in fallout4/data/scripts. If you don't have a scripts folder, create one and place in there.

Troubleshooting: On the first run, you might have to use Nexus Mod Manager and run it as adminstrator.
But mostly the game resists if you try to place QF_MS17_00022A08 because Windows has methods of trying to avoid any unapproved scripts from running and will sometimes try to fight it.

You can tell if the .esp is working if Jacob is named "Jake the snake"
I'm working on a reporter to detect if The script is running correctly.

Please let me know if you encounter any bugs with this.
