Hello,
Since the release of the game I have run many times into an annoying bug with camera 2. The bug happens when playing cam 2 and driving too close to an obstacle. It kind of behaves like if the camera crashed while the car did not.
To help you reproduce that, I have built a track (https://trackmania.exchange/tracks/view/41082: (https://trackmania.exchange/tracks/view/41082)) If you only press accelerate on this track, you should notice a "jump" in the camera movement while going into the cp triangle. I have also uploaded a replay on trackmania exchange.
Thanks for considering
