Character tag erroneously converted to an artist tag.

I'm not sure how to go about correcting this, but the character tag aosuke has been converted into an artist tag and given an artist page.

I retagged it on an older post back to char:aosuke, but the tag still retains an artist page.

For me, it's still an character tag (green).

Looks like someone resolved it and the artist has been given their own tag.
