Just did one of these races (B race) and as soon as the race started all other riders disappeared along with their positions so I had no idea where I was relative to other riders.
There was a lead-in which was most of a lap, and as soon as I crossed the start-finish line for the official start of the race (lap 1 of 3) all riders reappeared. I was near the back of the race by then which was slightly annoying.
Anyone else had this/know the cause?
Cheers
