Using a sarcosuchus to stand/sleep on air above a body of water.

Expected Behavior

There are 2 unexpected behaviors with this bug.

When you attempt to walk on a sarcosuchus from the shore, you should fall off of it, back into the water/land.
When the sarcosuchus swims out from underneath you, you should fall into the water.

Current Behavior
Currently, you are able to walk on top of the sarcosuchus from the shore, and it will act as a piece of land. If the sarcosuchus walks forward, it will not knock you off, allowing you to walk forward at the same time to effectively 'ride' the sarcosuchus.
When you are out in water, and the sarcosuchus swims out from underneath you, you will not fall into the water, but instead stay floating. You can also then go to sleep while standing above the water.

Reproduction Steps
- WIth a friend, log onto sarcosuchus and something else. (tested and works with suchomimus, allosaurus, rex, eotriceratops, ceratosaurus, megalania, spinosaurus. and deinonychus. Found nothing it didn't work on, so it presumably works on everything.)

Go to any body of water where the terrain slopes into the water at a steeper angle. Example (can be steeper, but not less steep):
Have the sarcosuchus go as close as it can to the land, while still staying in the water. The sarco should also face away from the land.
The other dinosaur should walk onto the sarco's back.
The two should walk/swim together at a similar pace until you are farther away from shore.
The sarco then needs swim out from underneath you.
The other dinosaur is now standing above the water. NOTE: You must be around at least 2 sucho lengths away from the shore when the sarco removes itself, or else you will fall into the water almost instantly after it removes itself.
