Regarding your "Advice Needed!" request,
Leave the obstacle avoidance features in operation.
Never rely on the obstacle avoidance features to keep you out of trouble.
Don't fly near objects, at least until you have several dozen hours of flight...
You need to fly carefully for the first couple of flights after a crash. You may in the near future get a strange error BUT if it seems to fly just fine and you see nothing wrong then I would consider it a cheap lesson learned and fly normally...
After watching both full flights, I can see the paths were very different between the two throughout the flights. . I will have to review the waypoint missions when I get my drone back to see if there's any explanation for this.
