Hello again, sorry I missed your answer. So I plan to reopen issue, cause I tried to squash my migrations again :)

I get this error again:

I have 126 migrations. I think that I don't have self referencing migrations, only merge migrations, referencing others. I think I didn't have any monkey patches. But maybe you could give one little example, how this could be performed. My django-named packages:

pip list | grep django
django-extensions                       3.1.3
django-pglocks                          1.0.4
django-polymorphic                      3.0.0
django-prometheus                       2.1.0
django-squash                           0.0.6
djangorestframework                     3.12.4
djangorestframework-csv                 2.1.1
flake8-django                           1.1.2
pytest-django                           4.2.0

I don't know where could I start debugging =/

Sorry for the late reply, but without your migrations I'm not sure how i can help you. If you can copy all your <app>/migrations/* and add them somewhere, so I can replicate it. You can delete all the operations = [...] but i need the dependencies = [...].

Or if you can create a dummy project where you can replicate your issue without giving too much away of your code/project? I would love to help you.

Cheers.
