Rider off-road

I’m having a very strange glitch wile riding on Zwift. Second time this happens on a ZTR race. In the middle of the first lap, the rider simple goes off-road and I lose the pack. What can be happening?

 

Though not as thrilling as yours, I had a recent unexpected excursion also where I left the undersea tunnel and went swimming with the fishes.

I was already soaked in sweat so didn’t mind too much.
