The chutes semi-deploy around 22K, which I believe is because they are linked to the atmospheric pressure. Full opening (default 500m) will not go any higher than about 1000m. It almost seems to be a MM bug, but that's a pretty stable/simple product so I'm leaning toward user error. Do I need to erase the MM cache files every time I change something? I've set the multiplier higher, up to *=8 (which should be 4000m), and still get the default behavior.
