Hey @alisandagdelen, I think I was able to reproduce it. I'll submit a fix soon.
Thanks for finding this!

@alisandagdelen I think I solved that problem, but unfortunately Kintsugi would still throw in such a case. This is because in "ours" change there's a file addition to a certain group, while in "theirs" change that group was removed.
