Okay, I've got a trigger once targeting four metropolice to begin their rappel (and yes, the 'waiting to rappel' flag is checked) They are above a func_breakable_surf with the BreakOnTouch flag on, so it smashes when they hit it. But when I walk through my trigger_once, nothing happens. Any ideas? PS the func_breakable_surf's are at an angle, if that might have anything to do with it.
