Casting strangeness

I've been looking throug ch_bsearch_skill_prefix and scratching my head... Because...

Say a character has a spell called "black hand". S/he does NOT have any other spells that start with "black". So... They try to cast it...

Character: c black mob
Response: You do not have that knowledge.

WTF? I've looked through the ch_bsearch_skill_prefix, and it's supposed to SKIP unknown spells... Why doesn't it pick up on black hand???

I've been working on this for a few days and JUST CAN'T FIGURE IT OUT!

Check skills.dat or w/e the spell is saved. Make sure it is set as a spell. Also, go through and make sure it has a gsn, so people can practice it. Just double check it all, or recreate it. Thats my guess. Then again, remember, I use SWR so mine is a bit different then yours I'm sure.
