Yeah, I hate that one with the castle!
nyuk nyuk nyuk
I do agree though, there are some horrible maps. I've got an ath based char and the amount of glitched out surfaces is rage inducing on some of the maps. The limited testing I've done seems to show that if the ground under an area of castle isn't flat it fucks with your run speed, but that doesn't make a whole lot of sense and I'm really not sure it's right :/
