in crushbone at about -145, -74
 

within a couple points of this spot I saw an orc run into the half-wall for a second or two and then warp away somewhere unknown...later to return with a half dozen friends.

most orcs killed in this general area run along the path, this is probably intended.... i've seen them occasionally try to run right at the wall instead and then warp away, or just run through the wall... didn't type /loc the other times I've seen it today.
