Also getting errors since the update, mainly in the Sands area of ZM. Arrakis was up at the time of first error, but now firing every minute or so. Architect's Reserve (requires Sopranian Understanding) is showing on the map although I'm currently still researching this on an alt. Pilfered Curio is flying only (for non-Venthyr, at least).

Many thanks for the fix to Architect's Reserve.

I'll also add the pilfered curio's alert to the flying-only list... I just need to get the vignette ID first, and I did this during the maintenance window so it wasn't possible then.
