That one may be tuned beyond its visible radius. The gravity variable to set those things works based on the center point of the obstacle and stretches outwards from there. In devmode, if you crank it up a bit, you will easily be pulled or pushed outside of the visible eccentric circles surrounding it. It wouldn't surprise me any if the default gravity of those things extends just beyond their animation.
Yea I think that's whats going on because there is a gravity thing nearby but compared to others it shouldn't have done anything. When I get to the space on the wall, the middle part is where I can jump from but if I slide down past that, even by a little bit, then I can't jump and just slide into the nearest saw.
