I now have knowledge on working with bits, and could update the editor. I thought your message was from years ago at first, since I rarely check this site. Good timing
Cool! Thanks for answering.
Apparently i can set the flag but it won't be written on the file.
While waiting for your answer i started coding my own save editor in c++ to make some practice with the Qt library.
I would really like to discuss about your save editor since i love this kind of stuff.
Feel free to send me a mail if you want ( setti93@gmail.com )
