This patch's purpose is to fix a problem with gargoyle flying over the Gargoyle Flight Paths in Ter Mur. As of today, the code from SVN won't allow the player to successfully traverse the Gargoyle Flight Paths. Also, it's impossible to completely cross the mountain ridge leading to the Shrine of Singularity just north of the Holy City.

This patch fixes all the issues with those. It will likely require some optimizations, but for now it's working. I conducted some tests inside houses with stairs and such to make sure I didn't break anything.

As usual, I am the author.

I have found errors where I am flying around in the first floor of a building and suddenly I jump to the rooftop. The client won't show me in the rooftop until I land, but my z property is at roof height and I can't access ground level items because of that.

Will need to review this further when I have more time.

For those who don't know which places don't work with the current POL from svn, these are the places I am aware of (All in Termur):
