Gazebo issues with standard VTOL


I’m having an issue with Gazebo using the VTOL air frame. Unless I re compile everything every time then the model seems to loose all normal behavior. I’ve attached a screenshot of QGC to show this.

It doesn’t happen to other air frames, just standard VTOL and it’s getting very time consuming having to re compile everything every time.

It works fine on the stable branch so I’m assuming it’s one of the changes made to one of the .cpp files in sitl_gazebo/src?

Thanks for any help!
