It has come to my attention that the newest version of the DMC3 Tools software allows you to select an option that enables cutscene movement with the Style Switcher 3 that comes with it. Unfortunately this option also enables moving in sections like the M6 spike room where it's normally not possible. If you use this tool to install the Style Switcher mod, make sure the option is ticked off. DMC3 Tools: https://github.com/644/dmc3music/releases/tag/2.3.0.0

Updating the rules to clarify this: "Doing cutscene movement in sections where it is not normally possible in the 2006 version is forbidden (possible ones: elevators on M4, M5, M7, M14, M12 Geryon defeat, M17 spike room.)"

As a result I have to reject some runs that have used this feature that went under the moderators' noses.
