While IndyPendant's observation is very keen and may prove useful, I'm quite sure I've gotten the bug in places no #poptype was specified, at least for water nations.

If it's linked to poptypes, it could be linked to certain specific poptypes more than others and if the underlying poptype is a problematic one, it could cause the problem. So, as Daynarr said, this is a very important thing. It's the first concrete clue since Strages Sanctus managed to reproduce the bug on a specific map in a specific province and a damn sight more informative and general than that one too.
