When I start the RTS portion during the second visit to Aonir's Blade, the workers won't start building anything or upgrading anything. Not sure how to fix this.

I have the same problem. Says there's plenty of resources at the top of the screen, but there's zero in the main outpost/whatever it is. So nothing can be built. I've restarted it and had the same bug. It repeated the conversation with the guys in the bottom right corner too both times.
