<Interitus> I've got a rotating room, a couple of brushes, some in an arch, parented to a func_rotate
<Interitus> in room one, where there's a pit, the second time I do the fling and jump down into the pit, I hit some invisible platform, move slowly, then suddenly pop down near the floor, and get stuck.
<Interitus> in room two, the room rotates so I'm on the ceiling, and I'm in midair, move towards the door and get stuck
<Interitus> I cant find anything in my map that could possibly be getting in the way

Attached is a screenie of room 2.

At msleeper's suggestion in IRC, I selected all, and applied a dev texture to everything. (except for triggers and areaportals).
His thought would be so that I'd see what I'm standing on, probably figuring it'd be a nodraw'd brush.

I still couldnt see anything.
