Orthomap - GPS misalignment and sliced

Recently I have more issues with gps misalignment, ie 100s of feet to the right vs google map and cutting off certain slices in the orthomap/pointcloud.
I am flying at least 70% overlap, DJI L1D 2c Hasselblad camera.

I run standard parameters in lightning odm and my docker odm.
I also tried with camera lens setting brown, same result unfortunately

Comparison - dronedeploy renders well.

Thank you for any pointers to fix.

  3. Did you fine tune any parameters? Which ones?
    No

Try increasing min-num-features (double it).
