Hi Utkarsh, I finally had some time to look into this issue a bit further. I have a testcase for you of an Ahmed body that also shows the weird missing of the data.
The case with some intermediate result (approx 400 MB) can be found here: https://we.tl/ZZwy4ZGL1K The case without that result (approx 125 MB) can be found here: https://we.tl/3dSqgyd4zG Hope this helps in finding the issue. Please let me know if you need more information.
