I had that issue using nyx too. It’s a problem with how nyx saves files it reads I think. Lots of comments here say it can be fixed by editing the x,y of the image in the notepad files of the game. Easier way is to copy paste your saves and settings, then re-extract from zip. And use UMM.
One exact reason why I prefer umm, now I don’t even have to install it.
Why use my X when it doesn’t work right…just for the ui? Would you stick your friend in disease and pimple ridden grossness because it looks nice up top?
I for one, would rather not risk it.
