I definitely have this issue. With so many different scores out there, I don't really have any idea what my grimoire is, except WRONG!! The calcified fragments were per character but only as far as getting ToM and completing the MoT. Grimoire is, and always has been (and always shall be) account based. Even grimoire earned for kills as a certain character feed the overall grimoire score, and don't subtract from it if that character were to be deleted. It is definitely annoying to have no way of knowing what your real score is. I don't understand how it can be so hard to fix, but this, just like the vendors not working in the app/website need to get fixed. Bungie, make the game great again (couldn't resist)!!
