Code that kills opacity animations

Just noting code that kills opacity animations, triggering message, "No controllable animations were found." I'm guessing that just removing the code isn't the answer, though doing so restores opacity animations without obvious harm in my limited testing (Flying Cauldron). I don't know how to figure this one out, unfortunately.
