I don't know. We just can't get competent staff nowadays! (And HB didn't even have the excuse of having to cope with things pre-breakfast on Sunday morning!)The story posting thread has the theme and genre reversed... I always look there first and was a bit confused for a few moments. It shows:
Theme:
COSMIC HORROR
Genre:
Fragment, fracture, and/or fractions
If you reverse those, you have the Challenge. Not sure if that is what your post was asking, but just a thought.
Anyhow, error now corrected so theme and genre are the right way around!
