I just tried to run the new race, and the rings turned almost invisible. I couldn't see them unless I was on top of them. Just to give a rundown on the chain of events, I activated the terminal, went to start the race, no one else was there so I used the emote (L2 + square), and just as the race was about to start someone else showed up. They ended up with a different countdown, so I was on my own, but after the race started I couldn't see the rings.
