Скачать или смотреть Trackmania (bug): camera 2 behavior changes after reactor

I've discovered a bug in Trackmania, where taking a reactor will change the behavior of camera 2 for the remainer of the run. This video illustrates this bug by driving off the edge of the road.

In the first experiment, reactor has not been enabled throughout the run, and camera 2 behaves as expected during the drop.
In the second experiment, I instead take the reactor and wait for the effect to end. Then I drop off the same edge of the road and we observer that the camera rotation is more "locked" to the car's rotation as normally.
I finish the video by repeating both drops in order to facilitate the comparison.

Although this experiment is constructed to clearly illustrate the discrepancy, this bug is also noticable during normal gameplay, especially when doing various jumps after a reactor has been enabled earlier in the run.

I hope this information is valueable, and I apologize for the unnecessarily academic writing style.
