Im just guessing here (Im in the spirit of helping mods lately, check out the draconian mod thread ), maybe its the fact that your monster #descr is ""?
Try writing "incomplete" in all of the #descr's and see if it works, I don't think anything else can cause a problem with monster description.
BTW, it might be the mod description (if it would have said there is a problem in the MOD description) which is that Im not sure if all regular punctuation is allowed, some games have special commands for things like apostrophes (&apos for that, atleast in one other game =P).
