i dont know if they patched it but if you hit the lock button while playing and leave it locked for like 3 minutes then fever is automatic cuz it thinks your still in fever mode until you start playing it agian
Its pretty easy once you figure it out, you have to go up and down the bumps without catching air. I cant find a video of it. So you just barely go over the tops of the bumps and you cant skip any bumps or you will get a slide. So yeah good luck!
