I've been trying to farm liturgy and gridskipper for like 2 days now, but I just cannot seem to make either drop. My method of farming has been master lost sectors (idk if this bug only affects lost sectors i haven't tried or know any other methods). I assumed it was the same bug that affected solo ops attunement, but that's just not the case. No matter what, any weapon I attune to does not correspond to some other weapon. It instead just drops any random weapon EXCEPT the ones I want.
