I assume you used the bone/joint behavior to create something like what you wanted - at least, that's how I would go about it, but I've never combined that behavior with platform before. Congrats on figuring it out (and I eagerly await your explanation ).
It's right here, actually, as of receiving a kind request from zenox98 to share the data.
The easiest way to make it work was with the "Physics" behavior, since it can handle linking, gravity, and additional force, via defaults, and events.
