Hi @Simone99 , thanks so much for the PR. Could you please add unit or regression tests. This is required so that in future the indigo does not change the behavior
Test can be added into python regression tests
e.g. https://github.com/epam/Indigo/blob/master/api/tests/integration/tests/basic/fold_unfold.py

or unit molecule

Hi @AlexanderSavelyev , I'm sorry I didn't run all tests and I didn't write mine before I created this PR.
By running all tests I found out I was failing almost all ones related to unfolding, so I fixed the logic underneath and wrote my own tests. Here you'll find the output log of all tests.
