If you encounter with different movements in QGroundControl like vehicle moving and rolling and errors like Horizontal Position,Altitude estimate etc. I guess it’s about ekf estimation. Probably you don’t reset the simulation completely. If you working in Linux try to check active processes (top command ) and if gazebo still running(it’s name look like gz orda gazebo) try to kill it. Also you can try to restart ekf from console screen in Qground (ekf2 stop and ekf2 start). I might have misunderstood the problem if so please share a few screenshots.

I am doing offboard control. I have script which kills all processes related to it and restart, but somehow, after one or few restarts this happens
