Good question: I believe that it will show you where they are but not generate them.

Reason I say that is by experimentation I have tried it and their is no significant increase in the games database file. Where as games with a lot of actually explored land have manifestly larger db files.

Thank you! I was thinking of ways to test this but havent figured out a way how... Maybe ill just remake the world and not explore the map and restart the building. Only spent a few 4-5 hours so not the end of the world!
