One thine i landed the drone in a field and one of the motor was blocked and i got motor unable to rotate error, but the drone was still trying to spin the motor. After 3 seconds with the motor unable to rotate, i got the error: motor error. I searched online and I see that the this error message is from when you lose a propeller but the drone had all propellers on it. I push down on the stick and it stopped. I also noticed the drone can fly upside down and not getting imu altitudine error. And also i can't stop it with CSC. One time it crashed next to me upside down. The motors was still spinning and after 5s it stopped and i saw smoke coming out from the right front motor. I pull the battery out. And the drone smelled like fire. I tried to start the drone. And i got power system hardware error. I got it to a repair shop. And the motor was burned and the ESC board melted. It cost me 250€. After that it worked fine. What could caused that?

There are some photos
