Hmm, I don\'t think there\'s actually anything wrong with the map on that very location. When you climb the stairs, you just rise so high that camera pushes through the ceiling. I don\'t know why the collision detection doesn\'t kick in there.
I get those graphical artifacts all the time, as I\'m running without camera collision detection. I\'ve been calling it idspispopd since the times of Doom 1, as that was the \"run through walls\" cheat code.
