Topic: Labo 03 Vehicle Tundra Rocks

Hello all,
I am playing Labo 3 and I'm in the Tundra area, there's a task to smash three rocks with bombs. The problem is a didn't fully read it and smashed them with rockets, now they aren't coming back! I've tried going to a different area and coming back but they are still gone.
Any help?

Thanks

Oh great, I will try

I changed to rally mode, had a race, went back and all good! I guess I forget due to sleep mode you don't actually quit the game or console.

Thank you, two areas left to complete!
