Yeah, I just spotted that yesterday while parsing out the NPCs for the Rise of the Drow Prologue. I've got a few very minor fixes to provide an update for - this will include blindness/deafness.
Multiple metamagics are on the list too...
No worries - glad you find it useful.
It is definitely a case of keeping an eye on the output for indication of spell parse issues - which it is obvious you are. :)
Always double check the NPC once in FG to make sure all the spells have parsed out OK.
