Think there’s a group of issues like this that I suspect have a similar cause.
Where I experienced something like this

I think the issue is alts doing things in unexpected orders and things like the command table, the abomination table and unlocking soulbinds having enable quest givers in specific phases that we can’t get to. So we never see the quest to actually turn these things on.
