Multibattery mission: restarts several tracks before abandonment point

Hi!

I looked at previous posts on this issue but could find none more recent than 2017?

Mavic 2 Pro, running missions through a 2020 iPad Pro, all of it up to date EXCEPT I had NOT upgraded the firmware on the Mavic. Previous firmware was updated in November 2021. I am now up to date and have not tried to replicate the problem since.

I was on the road, away from internet. I had multiple missions saved. Most were battery-limited (as usual) and I had no problem. One I had mistakenly saved with a 17-minute battery timer. On this mission, it came home for the battery change, but then restarted on the next phase from a point several tracks before the abandonment point, duplicating many photographs and significantly lengthening the mission by adding several battery changes.

I was likely manually taking over during landing, I usually do. I see that was an issue in 2017.

Also, I did not know about the feature to click the track corner when the line is blue (for checking flight path) to manually reset the point to restart the mission. I will know about that in the future.

Two questions:

1) Was my problem caused by old firmware or similar? Or is there another bug?

2) My mission completed with many, many duplicates. Will it cause any issue to load all these photographs into MME, OR should I manually delete the duplicates?

Thank you very much!
