Hello all,
thought I'd post this as it has happened to me twice now, the same spot. When I run across this place: http://s592.photobucket.com/user/tie.../bug1.jpg.html
...I fall through somewhere around the red circle. Afterwards I end up here: http://s592.photobucket.com/user/tie...a/bug.jpg.html

I can walk around on the water and "inside" the rocks, however I cannot jump onto any platforms or boats, I just go right through.
