Drones can often be a sticky subject as far as troubleshooting. First, make sure there is nothing lodged/twisted between the motor and propeller. Second, compare the height of the broken rotor to that of the others to ensure they are the same. If the propeer got pushed in toward the motor to the extent it would prohibit rotation, the broken propeler would be lower than the others. You could also try adjusting the trim of the drone to see if it makes the propeller kick back in. If worst comes to worst, you could open the thing up and see if any connectors got knocked out of place. Hope this helps!
