Small changes concerning balance, gameplay, or graphics.
Just updated to 3.0.2 and in my save when it loads the migration seems to remove my logistics roboports and logistics area upgrade, Energy ports were OK
The issue should be fixed with the next update, as for your roboports being removed, that should be fixed by changing some startup settings, as I've intended them to be, however due to a bug they were allowed to go higher by default.
