Saving configurations

I have not found a way to save my in game configs till now.

But for setting up a game, that does not need so much.
If you save the created map, and if you save the game setup after you choosed your settings, you can just reload it every time you want to start a new game.
All you have to do is to add your player empire to the game after you loaded the game settings.

Use the "Save empire" after you sarted teh game and set up your configuration as you like.

The next time you start a new game use the load empire button when asked to add a new player.

It used to work in 1.13

It seems a tad buggy that save empire button, I recommend staying away from it.

if you do the save empire button it will save all those settings and any custom views you've created, but.... it will also save the tech level you've attained. So if you try to load that empire next time you will need to have the second to lowest tech level clicked. at least that's the way it was with previous to v1.17, I don't know if that's been fixed.

Another thing to try is to set points to 5000 and all tech levels, then load your empire, then change the tech level back to the starting level. I imagine that all these workarounds wont be needed soon (they'll be fixed in a upgrade).
