Because I've found that needing the "Quest" option checked is necessary to find certain collectables (especially items with hidden quest flags), I kind of wish there were ways to only filter certain types of quests. ("Locked" is currently unchecked).

In this case, the breadcrumb quests that really don't count towards anything except the "3000 Quests Completed" achievement for the Seeker title, so it would be useful to be able to hide them.

So if you do the followup and intentionally skip the breadcrumb, it'll hide for you.

You probably shouldn't do that though.

This is ancient content for this character. It has Vanilla-level Loremaster. This particular one is showing because it's saying I could do it via Party Sync because I already finished the followup quest (hence the green checkmark). Wouldn't that make this locked anyway?

@DFortun81 This is an odd situation. The quest The G-Team has 2 crumbs leading to it: Exploring Gnomeregan and Home Sweet Gnome. This character seems to have done neither crumb but has done the following quest. I think the lock criteria aren't kicking in properly here?

This logic got broken a while back and I've since fixed it.
@kcoderhere can you verify this situation is fixed on latest ATT for you?

This should be fixed, please reopen if it is not the case on latest ATT.
