How do I complete the "Everyone's A Critic" mission?

Kevin Smith asks me to retrieve his film reel. I get prompted to switch to sensor suit, and activate it - it creates a trail of coins going up. Catwoman brags about having stolen it, my senses tingle again. I activate the sensor, and it creates a new line of coins, leading... Nowhere. No obvious sensor point or anything else.

Is this mission bugged? (I'm on 360.) Or is there something non-intuitive I have to do here? If it is bugged, is there a known workaround?

Solution 1:

You'll see some trash pop up (pizza boxes and a trash can). Smash it, scan again, go down the ladder, then repeat and follow the trail of studs that leads to more trash cans back where you came from, around by the central platform, and then on the platform to the right of that. Source
