I was playing on gm_skystation V 1.0 when i decided to test if the arrow got stuck or not in the air, it didn't, but in that map if you jump off the station it kills you, the thing is that when i used god mode to test some other stuff, i noticed that the arrows got stuck EXACTLY where the trigger_hurt starts, so maybe the arrows stick to things they shouldn't like triggers and nodes because another guy was also claiming that he could shoot arrows in a higher part of the map (possibly one with no nodes or triggers).
