I have suffered the Ghost Fragment Darkness 3 glitch where the Grimoire Card doesn't acknowledge despite picking up the dead ghost in the dark room in the Lunar Complex om Earth as you head through to Skywatch. The ghost is obviously no longer there so I cannot recollect - anyone know if there is a fix to be able to get this Grimoire card if this has happened to them? I ca see from comments online this is a common experienced glitch.
