I made this mod for my personal use, as I didn't like the resource limit on nauvis that space exploration introduced in version 0.1.125 and was getting annoyed of manually overriding the "homeworld_resources"-function on every update of SE, as some others do.
What this mod can do: It prevents SE from changing the map generator settings on nauvis as well as the size and richness of existing ore patches. This should work on a new game as well as on an existing game where SE was not yet updated to version 0.1.125 or higher. In this case it should be safe to install this mod and upgrade SE simultaneously.
What this mod can't do: Revert the changes on nauvis that SE > 0.1.125 did to an existing game. As SE deletes the old map generator settings there is no way to get them back...
Use this mod at your own risk, I have not tested it very well yet.
