Note: I don't know if this is newly discovered, but it accidentally happened to me yesterday morning.

While jumping towards the ladder in Garfont Village I managed to clip through the ladder and wall out of bounds.

I have a video of it (recorded on my phone so low quality) but I have managed to recreate it about 8 times within an hour. (so I could try to get a better quality video easily)

I don't know where I can upload it here, but I think when you jump towards the ladder [that you push down to make a shortcut to the upper section of Garfont Village] at an angle (approx 75-80 degrees from perpendicular) it tries to reposition you towards the ladder, but pushes you too far and you climb through the rock.

I've not made too many tests about possible exploits to utilize this in, but I just wanted to publicize this so others can use it.
