I've been working on a couple of new scenarios for HSC lately. In this route, the signals show up clearly on the 2D map while editing. Or at least they did so until I verified the game cache on my computer yesterday. Now the signals are no longer visible in 2D. I've never run into this situation before and am hoping that someone can tell me how to make them visible again. Let me just mention that I looked at the 2D view's properties fly-out and everything is checked.
Thanks,
Tom Pallen
