Expedition Scout's Packs do not show on Taldraszus and Azure Span. I tried disabling/enabling, resetting hidden nodes and reloading - nothing changes. They work flawlessly in Ohn'ahran Plains and Waking Shores.

I somehow fixed it by enabling them in submenu "Zone/Talraszus" and "Zone/The Azure Span". I have no idea what's going on 🤷

It's separately disabled per-zone for you in those zones -- note that "currently hidden in this zone" bit in the tooltip -- which you can change in the zone submenu.

I should maybe have the top-level checkbox reset/override the current zone setting if it exists, such that toggling it removes that override.

I think a hint in the tooltip where to change this override would be good. Thanks for clarifying this.
