I made it a few minutes into Smart Bracelet (2014) before this happened. The BMNG layer was off, relief layer was on, and the lat/long grid was on. I'm running Win7 x64 with 20GB RAM, an i5 2500k on a stable overclock, and an HD 6870. Command is installed on an SSD. I've attached dxdiag.txt to this post (I... think?).
I haven't seen this issue with other scenarios yet; I'll see if I can reproduce it on this PC/a different one. The UI quickly became unresponsive while I was playing the scenario, but the game itself didn't lock up until the unhandled exception. Time mode was set to no-pulse.
