No collision windows in Amber Hand Stronghold.

There are some windows with no collision in the Amber Hand Stronghold. You can hop through the window stand there and shoot outside them.
It seems to be all of these white "grid" frame windows.
I haven't tested it outside of the "Explore Map" mode.

I've just confirmed this works in a real match too.
