My AOS app has updated recently and it looks like the main update is to add a Malign Portents tab. However, under the battlescrolls tab the faction drop down button has 'aelf' appear twice and when you click on it, it crashes out.
Dunno if this is a straight up bug or an unintended hint at another faction on its way.
Edit: Scrap that - the update has made the app screwy - don't think there is anything to read into.
