I'm stuck :(

GUYS I'M FREE LOL

Hii, I need the rock crusher, but to obtain it I need the spirit flowers, I have only one, bcuz I already used Gwen's flower, and I have Summer's. To obtain another flower I need to finish the quests either from Atul or Alice, I already have Giovanni, Astrid and Gustav in the boat. But now all of the quests need me to access areas that would need the rock crusher. Can somebody help me?🥺

Edit: Finally got it, thanks to Chilli for pointing out my mistake about the location, I forgot where the Nordweiler is located, now I got it. Love alwayss, byee
