I'm guessing that the author of the map has neither subscribed to this thread nor visits this site regularly, but in case they (or someone else) does who might upload a better version, there are some additional errors i have found, including:
- provinces 111 and 102 erroneously have a land connection; this connection should be river crossing only.
- - provinces 42 and 59 erroneously have a land connection; this connection should be river crossing only.

This has not been updated, but it is possible to fix it in the map editor. I have done so, but have failed in being able to upload it here.

Has the missing border been fixed?

187 - 190 has a missing border, top center-right in the screenshot

Thanks for the update.

Ditto, loved the Dom 4 maps, including this one.

One of my favorite maps from Dom 4!
