Reminder: You can cancel and resend your Fragment
Because the Creative Writing is a Virtual Action, per the rules for Virtual Action:
Until a virtual action is resolved, it is pending. A Storyteller may cancel a pending Virtual Action by privately communicating to the Publisher their request to do so.
Creative Writings don’t get resolved until the Judging is posted, so you can cancel your Fragment and resend it at any time until the Judging is posted.
