So I was on my hunter grinding out my 45 calcified fragments but found something rather odd when I reached 45.. The quest line didn't continue. I have completed every quest up until this point on my hunter and there is no reason at all that I should not have the quest for phobos given that it is next (and last) in the lineup of missions for the gun. I have checked the abandoned quest log and read and re-read the 6 quests I do have active but none of them regard the quest line at all or any of it's requirements. the only possible solution I can come up with is that either the community is wrong about the simple 45 calcified fragments and there is actually a requirement for specific ones such as the nightfall completion on the dreadnaught or simply my game is glitched. Either way I would like an explanation and maybe some way to fix it.
