Why won't the Regis activate?

Question

I'm playing Omega Ruby and I am hunting down all of the legendary Pokemon. I know where they all are and how to get them from my previous playthrough of the game, but I tried getting the Regis just how I did before, and it didn't work. The earthquake that unlocks them was never triggered, even though I had Relicanth in the front of my party and Wailord in the back. I looked on YouTube to double check, and I wasn't doing anything out of the ordinary. Does anyone happen to know why it may not be working? (and, yes, I had a Pokemon with Dig in the party)

I already know you're not an idiot (not sure about the other guys though). I'm asking these questions because I am an idiot.

Watch this video, it's a gameplay of catching the Regis.

Please tag this omega-ruby-alpha-sapphire. You know, because I’m really into using the proper tags all the time.

Use the move dig next to the ice crystal and it puts you out next to a stone regigigas

I don't think there are ice crystals in the Sealed Chamber.
