I need a refresher: is it possible to conquer a province next to an un-cored province that I might have taken shortly before? I'm looking to see if I can conquer Oberkärnten (a core of releasable nation Styria) after taking Friuli? Or is that not possible until Friuli is cored? See image below for context (Oberkärnten and Friuli share a small border, fyi).
