The game is treating me as if the wall is the floor. Jumping off puts me essentially in free-fall, since the game is treating the wall as the floor even though gravity still is on the true floor. Tough to explain exactly, but I spammed /spawn in Gahreesen to get to the Maintainer's Nexus since you can't get there yet just normally playing. (and flymode is a tad bit tricky to line up right)
Wall is great though, I can run all around and up the ladder without any trouble. I would guess the chair in the one room is what was used to set the "obstacles" in it?
Edit: I wasn't around for UU when the wall worked, but it looks to me at first glance that you walk sideways up it, which could explain my dilema in the prison room...
