Post in forum #265727 - [Announcement] Tag categories for existing tags can no longer be changed via metatag

I'm now getting a 500 error if I try to create a tag via a post edit (without using metatags). (21f735c6169d85cf3e5fed5d0d355ab7)

Posting here 'cos I figure it's probably related to recent changes.

In the meantime if someone Privileged+ could add a vertigo_(character) tag for post #1721941 that'd be great. People already trying to re-add the artist tag.

Edit:
Fixed, thanks.
