The dinosaur in a perpetual falling state and is completely immobile.

This dinosaur is in a constant falling state and completely unable to move.
The WASD movement keys and jump key are also unusable. The suicide code cannot be used because the creature has not been active long enough.
The only workaround is to delete the dinosaur and recreate it.

I believe this is a cave‑specific bug in the novice cave. If players accidentally trigger it, they should be able to move out directly, instead of having to delete and recreate their dinosaur as the only workaround. Below are the coordinates for this location (X=-271990.349014, Y=-359164.449473, Z=150101.020301)

I suggest adding a way for trapped players to move out directly, instead of forcing them to discard their character.
