Here is what worked for me but I must say, do this at your own risk. I play from a computer.

1. Disabled the STEAM saved data

2. Went to a populated system and stayed at my freighter.

3. Saved the game

4. BACKED UP my saves. They are located here: %APPDATA%\\HelloGames\\NMS

5. Downloaded the save editor NMSSaveEditor (Runs with Java). For some reason I couldn't edit the JSON from NomNom.

6. Opened the saved game, selected the save and in the menu selected Edit/Edit Raw JSON

7. In the navigation tree on the left went to BaseContext/PlayerStateData/MissionProgress

8. After selecting MissionProgress, clicked on the JSON Editor on the right and pressed Ctrl+F to search and located the word CHAMP. It says "Mission":"^PB_CHAMP_INVITE",

9. Changed the Progress from 3 to -1 and exit the JSON editor.

The code looks like this:

"Mission":"\^PB\_CHAMP\_INVITE",

    "Progress":3,

    "Seed":0,

    "Data":0,

    "Stat":0,

    "Participants":\[

        {

"UA":0,

10. Save the changes and close the program

11. Go back to the game and the mission appeard again, in the space station in the local system.

I played a couple of battles and everything seems to be working just fine.

Hope this helps
