Losing your marbles - quest

[lfallenangel75]

So, I'm with Hades, I lowered the drawbridge and it fell. I went down, fished up the podium, turned the wheel and directed the lasers how they were meant to go. I pushed the big block to the last one before pushing it under the bridge. But, now it won't let me interact with it to give it the last push under the bridge! Am I missing something? Why isn't this working?

I had the same problem, just went back up top and pulled the bridge up. Went down and I was able to interact with the marble. Then you can lower the bridge again
