People often don't ask for permission because there is no way to get in contact with the original creators anymore. Or in Nicks case, since he made the sets for JJ2, we tend to think that it's okay to make conversions/extracts out of them. Honestly he'd probably be happy that we fixed the masking and tile arrangement.
