Not selected checkpoint in the race (Forza Horizon 4)

Play yourself, play, Goliath, put a lot of laps, sit. An hour or two, at the third hour, when crossing one of the checks it is not allowed. I drove again, drove to the other side and drove, hitting the flag pererezannym car, paused, took it, opened the map, closed (out of desperation), nothing helped. There is a way to solve it? Sorry for the 3 hours of suffering to lose without reward.
