Bodyguard B Ignores Divine Shield

I am simply amazed at this. It seems like it's a bug in general then. There shouldn't be much of a reason that an attack would be guarded once and then not again for the same attack. My last assumption is if the target missed you. If it misses, it would remove a charge anyway, right? Does a miss display "Guard" or does it actually say "Miss" when you avoid? I mean, I highly doubt you'll avoid the monster that much. Ghost pirates have 121 accuracy (sqrt 11) and Bodyguard B has 225 accuracy (sqrt 15). I can't imagine something we'd be missing otherwise. It just seems really buggy.
