I've just loaded an experimental change to FirstAid to let it handle 'hidden' limb afflictions from NPCs, making use of FirstAid's built in prediction system.

Yes, this may sometimes waste a mending application. No, that's not a bug, it is part of how the prediction system works. Please file a bug for any other weirdness that arises however!

Penned by my hand on Quensday, the 6th of Niuran, in the year 470 MA.
