It does seem to skip it in the script, though there's two issues there: One, that long, unsightly hang while it seems to try and modify the MCD settings (and then stops, or fails to, or what-have-you), and two, what if I also didn't want it turned off on other signs? When I'm not trying to optimize my turns there, I use the O.A.F., and as long as I don't have 100 ambient ML from the squeezes, even the 11 ML from the MCD won't put me to the next tier, and thus spares a turn of Coated, while allowing me to "maximize" the ambient ML to get the most out of thwacking the slime.
