Venice, stuck in St. Mark's Basilica four trials

[zioStatiUniti]

I've hopped and platformed my way around the entire basilica grabbing all four of the stupid hanging gizmos. Three of which rotated parts of the mosaic on the floor. The fourth puzzle only made a click sound . . . and. . . nothing. Now I'm running around trying to figure out how to fix this. Running back up and hanging from the gizmo does nothing. Is this a bug? or is there something else I need to do? It certainly isn't clear what you're supposed to do beside grab/hang from the four devices. Any help is greatly appreciated.

Grazie

You might not have made it in time. Go and stand on the 'pad' again, and redo the trial, and the nsee what happens.

Unfortunately, stepping on any of the platforms does nothing. They no longer move when you step on them.
