Great Crates! that offers Crate of the Art & The Superbloom
are weekly quests ( even though the crates ones aren't marked as that on WoWHead ) that make it so the questline is not marked as done unless they're finished every week.. so far I know they're the only repeatable quests in the addon, please remove them or make them marked as done forever once done one time.
