Can somebody please help me with this question or point me in the right direction to somebody that can answer this. I am trying to mod the theives guild to add more light sources, I have no problem with adding tourches or light points, but I do have a problem with editing the file again. What I mean is that the creation kit saves the file as aa.esp but when I re-edit the file it will only save as aa1.esp but the new file will only have the new changes not the ones from the old file. So I have to load aa.esp + aa1.esp to have all the changes, So how to I edit 1 file to have all the changes and only 1 file. Or is there a way of merging all the changes I want to make and saving them as one file.
