Assuming the flight logs that are in the system are the ones that had issues it looks like there were pretty strong winds our of the east that were blowing that light aircraft off the course. If this happens it won't take images properly and can appear to have issues flying. There would have been errors about "strong winds" in the Aircraft Errors panel since they are showing up in the log files.
The Mini 3 is a bit stronger so it may have been able to handle the winds a bit better.

You can use this older version for a while but I don't think it would have behaved any better in your situation today.
