Buggy quest glitch – OK K.O.! Lakewood Plaza Turbo Review

I love this game I completed it but when I enter the buggy quest, the screen goes gray an onl K.O. Is visible. If I walk forward, the road shows, and the buggy sounds are still present. Please fix this. P.S I want to play as other characters!
