YugiStardustITA I didn't realize that the Above Reproach lifetime reward blocks certain disgrace scenarios, but maybe only real ones? At any rate, this older page is mostly accurate:
https://www.nraas.net/community/StoryProgression-FAQ-Celebrities
The main difference to now is that the options varions StoryProgression add-ons enable have been rearranged, and the module you need is SP Relationship, in addition to the base SP.
If you don't want to deal with StoryProgression and everything that comes with it, NRaas Retuner would allow you to set the lifetime relationship loss to zero rather than the current 10. Retuner doesn't do anything unless you use it to change some value, so it would have no practical impact on your gameplay outside of what you chose to change with it. This is the path:
Retuner > Settings > General > by Tunable XML > Sims3.Gameplay.CelebritySystem > Celebrity Manager > kLTRLostFromDisgrace
There are also a number of other options under Celebrity Manager that you could change if you wanted. The MaxAccusationChance is per celebrity level, I think, so you could set all of those to zero to block the system entirely. Or you could set kFalselyAccuseMinDelay and kFalselyAccuseMaxDelay to very high numbers. They're currently 1440 and 2880, respectively, in minutes, so one and two days.
Sometimes the game needs to be reloaded after changing a Retuner setting in order for it to apply.
I answered your other question in your original thread since that's where we started talking about installing those mods.
