It's the second post in the thread.
I still have to update it though. The traits should work, but ethics and civics require manual updating.
I'm currently not able to update for a while, but you can find the values easily by yourself:
Edit the 00_defines.txt file in ...\Steam\steamapps\common\Stellaris\common\defines
You change the ethics and civics points to two easy to find, but different values (like 134679 and 976431), it should be unique in the game memory. Then start the game, look for the values in cheat engine. The addresses (stellaris.exe + some value) will be static until the next game update.
Save those addresses and close stellaris.
Change the 00_defines.txt back to what it was before. If you start the game now, you'll be able to edit the values.
