Scry from Vaal Temple Bugged

Yesterday I encountered the Nameless Seer in the Vaal Temple through the Mirage league mechanic. I scryed the City Square map which did work as both maps got the purple outline and City Square dislayed the Vaal Temple Cards on hover. The scry seems to have persisted until I logged out, as when I logged in today it has disappeared.

I'm not sure if you are even supposed to be able to scry the map or not, but for whichever way it is intended, this probably isn't it.
