Dont worry, it happened to me too.
You either have to;
1. log out and try again
2. delete the whole chapter and re-post
3.close down ficwad and reload it
4. all of the above (works best)
hope you get it sorted, i know how frustrating it can be
Thanks I'll try those now.
Yeah its very annoying. I was like 'Nooo!'
