Dinosaur model ignores terrain collision

The dinosaur model can pass through terrain obstacles and get stuck inside solid geometry, with no way to get out on its own.

My friend's Hatzegopteryx used the Flail ability, then clipped directly through the Waystone and got trapped inside. Other control inputs and buttons still function normally.

Using Flail should not let Hatzegopteryx pass through Waystone collision. The creature should not get stuck inside the object. Dinosaurs should collide with solid terrain. They cannot penetrate rocks or other terrain structures and should not become trapped inside.
