Update: 7.042 is out just to hotfix an issue in the last release where loading an MP game could do... "strange" things with the number of metal deposits. Bear in mind that if you have a save from 7.041 with 300 metal deposits on a planet, it will still have that, but a save from earlier will have the right amount.
On the starting-a-new-game-with-4-players one that's the one I found and fixed right after my post just before this. And when I loaded the save you just linked the metal amounts looked right (highest planet had 14 spots, most significantly lower than that) so I guess it was somehow related to the same bug.
