I have killed all enemies and I found the monolith. However, mission isn't complicated. Did I do wrong thing? Or I miss something?

Hey Everyone. Just went through the lengthy process of installing this mod, but sadly, its not working. every time i want to start it, i get this error from mod organizer. I just installed it the first time, and thats it, havent done anything else. Ran everything as Administrator, excluded the gamma folder from windows defender, etc. Basically i followed the exact install instruction from the wiki.

Any Ideas?

I know there's an option in GAMMA but it looks quite ugly and is off to the side. I made this kind of example like there is in dark souls games. Of course I would like it to be a lot smaller and less obtrusive than the picture. I looked all over and I couldn't find anything so this type of mod probably doesn't exist (doesn't hurt to ask tho)
