Hi there,
This is probably not the most game breaking bug but something I found just by riding a route. If you select the Snowman Route, then instead of going up the Grade new hill (after the Itza Hill) and turn right to go down instead, you can get stuck in an infinite traffic circle loop. Essentially my Avatar did infinite loops on the traffic circle at the bottom without exiting any of the areas

It’s a feature. On the Chasing Tour discord, there has been discussion of trying to get as many riders as possible on it to see if they can create an infinite Ouroboros of exponentially increasing draft. A draftnado.
…well if you don’t select yourself where to turn 
Did today ZA workout #5 in that route and end up going round after round at … OH it has segment 
Summit city velodrome 
So maybe this is planned “bug”. This can be kept
