When youre gliding you can shoot the grapplehook from your hand and pull yourself around at insane speeds. You also cant redeploy your glider after you jump after using the grapplehook

Do you have a video of this issue?

@Jeryn99 i recorded this behaviour.https://youtu.be/TA2dHJ4t0z0
After using the hook during the flight, you cannot jump off the glider. The space bar just doesn't work.
Also very rarely, the damage from the fall seems to accumulate. That is, after flying and strong accelerations, when you land, you just die from falling damage. But I couldn't repeat it on video

When you use a hook, the third-person camera just goes crazy. Only the view from the shoulder works, which adds some kind of mod. Apparently it works because it is tied to the player's model.
Also, if you remove the glider after using the hook, the player will crash into the ground at a cosmically high speed.
