So, apparently I cannot make custom nations in this latest version of M&T. Because whenever I paint a custom nation with more than two provinces, it CTDs with the classic Paradox Reporter Window opened.

Because of this, I got a few questions:

For those who aim to make their own nations, do you also experience this?
Am I forced to revert back to an older version for this to work?
Did the .06 'Patch for Custom Nations' break this mod?

Thank you for responding in advance.
