I decided to make a new character and when I looked through my mod list I found CPRS.esp, and I have forgotten what mod this is. It got no description and I cannot find any readme file saved for it, anyone who recognize it?

No idea. I tried googling it and it doesn't seem to turn up much. It was in one or two people's mod list, but with no indication of what it is.

If you open it up in the construction set, you'll see an asterisk next to the cells or items that it modifies... maybe you can take a look and figure it out that way.

I finally found the readme lying in the wrong folder, it was the Center for Provincial Religious Studies by Nazz.
