I just crashed the SITL plane twice. One after another (new connection, new download).
I added a mission around my country with 10, after that a 50 times speedup.
Both simulations caued an EKF Lane switch than crashed to the ground.
Very same effect like in these threads.

Auto takeoff worked well, FBWA seemed ok at first, then all hell broke loose. You’d think we would have been safe at the worlds biggest flying field!
flight controller is a cheap Pixhawk 1. about 100 flights without an issue like this, but of course, only about 10-20 flights on Arduplane 4.1.x.
I would really like to know if this is a bug in EKF3 affinity switching, or a consequence of using a cheap flight controller. Would a Cube Orange have done the same?
We had a strange behaviour a few days before.
We run ArduPlane 4.1.0 this time. In the setup time, while on the ground, disarmed we got orientation changes and velocity error messages. We did not risk it to fly.
-Pixhawk cube black
-Moving baseline configuration for orientation using 2 F9P modules (Drotek Sirius and Drotek DP0601)
-Compasses turned off becasue above reason
-Good GPS reception on both modules
The plane was disarmed so we g…
I added two logs from the simulator.
