Actually, I tried having a knife in hand, and Nate promptly equipped his RU556 when Aiden appeared, but it has a basic battle sight. I don't think having a custom sight was the issue because that's what I had equipped. I uninstalled STS but that wasn't it either, or FDI. It started up the moment I turned DC back on, so that was a fun discovery.
I've had someone tell me to try turning off Dialog Camera, and it hung before the first meeting got going.
