one of the funniest bugs/glitches, in a hunting game where for some reason in the lake of the Yukon Valley map they forgot to set the collision with the water allowing the player to enter and hunt the animals from the water without needing oxygen.

The player can completely immerse themselves in the lake, obviously only a part of it lacks collision, allowing you to walk underwater as if it were an ultra-terrestrial being and the fun thing is that you can ambush animals and hunt them while underwater with the only downside being that you will not be able to see their position.
