This has happened to me before and I resolved it before, but…, I never really understood how I managed to resolve it. This is a mission I fly once per month and the flight plan never changes but this morning it took off, climbed to about 50ft and refused to execute the mission informing me that there was a change.
The only difference this morning was that I launched from a location roughly about 30 to 40 feet away from where I normally launch. So after 3 attempts to launch from this new location which, like I stated was roughly 30/40 ft away I moved back to where I usually launch and it turns out that appears to be the reason for the flight change and refusal to launch.
Is this normal behaviour? The launch location is not the first waypoint. That’s actually about 120ft away and at a height of 150ft.
