Reported
Reason: "Tutorial suddenly restarted and got stuck in a loop of chapter 4.29. completing it will freeze touch. Restarting it will loop over to same result. ///////////////Me too".
Checked by myself.
I have no issue whatsoever to pass 4.29.
Be sure to keep your heroes up to avoid eventual error and you should be fine.
You can see my team on the screenshots below. All my gear is between 3-5 stars and leveled to their maximum.
