To add colonists do this (it can't be changed in savegame)
1. Go into your DB folder
2. Make a backup of your traders.csv
3. Change the original one into traders.csv.txt (accept that this might make it useless at prompt) (you might have to change folder properties to display file extensions)
4. Open traders.csv.txt with notepad
5. Change ...;END to ...;CHI;END (make sure that IGC doesn't have a column for CHI already, if it has then there is where you should change stuff)
6. In each following line, at the end, add 300;
7. Save and exit
8. Rename traders.csv.txt back into traders.csv (accept at prompt)
9. Enjoy having 3 colonists per year for the entire game.

Stability you can change in savegame, open it with a text editor, search for 'tag = CHI' and when you find that just below a 'country = {' then just scroll down to the next 'country = {', just above that there will a 'technology' where stability is mentioned and can be edited.
