I don't think I quite understand how these cloned checkers work. I had one removed because my type of challenge is no longer accepted but I didn't realize that. I changed that type of challenge to something that would be accepted and tried to clone a new checker. I get this message - GC-Code already seems to be tagged with a checker. I would like to clone the checker for GC5F9PZ but presently can't. Any help would be appreciated.
