Hmm interesting. I do hope Annie will explain this strange phenomenon in story. While thoroughly researching it :P
While it was mentioned, some crawling spaces can be accessed while crouching. It is done by walking into wall and then crouching while still moving. That has effect that you can get stuck between segments of map. It is happening all assets maps, just not everywhere.
Also just a question that comes with previous thing. Will you add scenes which will take in consideration any small enemy can have sex with Hailey in crawl space? Now if Hailey dong get knocked into a ground right a way, it causes clipping of the scene with map geometry.
Thanks again, good wind
