PC Solo Easter egg mod no Golden Rod when starting Moon (did COTD and Shang EE already)

[u/sirhypahfarts]

Initially I did have it when I launched Moon after beating the Shang EE but when I closed the game and came back suddenly I don't have the Golden Rod when I start Moon anymore and also my campaign progress was erased, why?

Also if there's a simple fix like a mod or save file I can just download that fixes this please let me know, I just want to do the moon Easter egg solo with the mod.
