What mod, (or bug) is this screenshot cutscene on the Ravager from?

[Erdan5 0]

On Darth Nihilus's Wookieepedia page, and a section page for The Dark_side_of_the_Force Legends page, it shows this image above of Darth Nihilus evaporating into Dark Side Force energy.

The file name for this image is "NihilusDissolvesOnTheRavager", uploaded on October 22, 2020 by a user named "Ruthless Xero". The file says it is a screenshot from the game of Star Wars: Knights of the Old Republic II: The Sith Lords. However, that doesn't make any sense. In the original vanilla game, and the Restoration Content mod, (which this screenshot seems to based off of give the lightning stemming from the red dark side energies), Nihilus is killed in a bossfight with you the player, and in a cutscene, he falls down dead to the floor. It is only then that Nihilus dissolves into dark side energy and he fades away with it. The Resotration Content mod is the same, Nihilus is lying dead and dissolves into dark side energy like in the game, but when he does a burst of purple lightning comes out and zaps Canderous Ordor and Visas Marr.

Given the presence of the purple lightning in this screenshot, it seems like this is from the Restoration Content Mod. However, both the vanilla game and the Content mod both show Nihilus as lying lifeless on the floor for a bit before he disintegrates into dark side energy. As shown here...

So what's with the Wookieepedia image of Nihilus standing up when sublimating into dark energies? Is this another mod variant, bug, or something else? I would like to know.  Any experts here who know if this is a mod or bug?  If it's a bug, how common is this bug?  If it's a mod, I would dearly love to know the name of this mod and if it is related to the Restored Content Mod or not.  If it's a mod, is the cutscene(s) different?  I have tried looking it up and can't find a mod for this.  Let me know if it is just a bug too, any help would be greatly appreciated.  Thanks.

(P.S., I am new here, and I love Knights of the Old Republic, especially the second one.)
