DJI Avata Baterry installation error because of broke prop

Fly with Avata and what to go manual and in that time it start wobbling and get battery installation error, slowly come back to home point and inspect drone. I see that one prop is broken and think that not original props was faulty and broke so easy in middle of flight, but then found that on GoPro mount I don't have tighten screw. Watch recorded video and see that it was unscrew and hit prop. So before fly check GoPro mount screw.

I'm surprised it still flew with a broken prop blade. What an odd error though to indicate a battery installation issue for a damaged prop. If I ever see that error, I'm landing right away!

Wont land in grass, so put in normal mode and fly to home. Wasnt so hight to fall down heavy if battery lose connection.

You are so lucky, it still flying, not fall down when the props are broken How is the inside part of your propeller guard? Is it scratching?

Yes, a little bit.
