I got on the velociraptor, and first thing I did was press E cause I was curious if I could get off. I went shooting in the air at high speed, but the camera didn't follow me. As I didn't fall down, I restarted from the checkpoint and tried it again to see if it would happen again. It did. Only this time I saw my character fall down (on the velociraptor), and right before she hit the ground, it crashed.
