Pathing issue

[takataka]

Sometimes on open expanses of land, a big square portion becomes inaccessible, forcing me to run in a broad path around the edge of that square to get where I'm going. This happened just outside of... I can't tell, but I think it's Eyesocket? If I'm right, it's just south of Eyesocket this is happening. Not sure if it's just that area of land or a mechanical bug, though.
