I have removed the offending 'node' which was on the other side of that wall. It will be 'fixed' when the server next restarts, no script update required.
In future, please don't post such a shit photo, enormous, on its side, cutting off the radar etc. it's like you tried to make it as difficult as possible for me to find that location. And it's not even El Castillo Del Diablo, it's Las Payasadas ._.
