That was an overzealous fan, and they were sternly talked to. If a mod needs to delete something, they'll delete something and give you a polite explanation. Normal members are not to take mod duty into their own hands and should be reported for doing so.
Now, regarding the code... I THINK I see most of what you're going for but I built the DLC system to check to see if a DLC file was present and loadable before adding the character to the map. I fear setting their _met variable to 0 as a default will hamper things later on when I put the unlock code into the main story (for those characters that require it) but I haven't fully written and released a DLC character yet so I have no idea if changing the code will screw things up lol
