In my game with Unfallen every minor faction have "chance to increment" at -50 (see screenshot). That leads to the situation that only base faction is growing (with +50) and I don't have any chance to become new minor population. Investing in luxury to improve growing of a minor faction leads to double the -50 value with the result of -100. Is there any chance to become the "chance to increment" positive? What is the mechanic of this feature?

Here you find the save were every minor faction have -50 "chance to increment" from turn 124

Test 27.sav

And here is save file were only Guardians have -50 "chance to increment" from turn 56 

Test 7.sav

You can look also at this thread with other bug I described:

Trade Route No Score Points

Problem isn't solved. You'd expect malus to be lifted when law is disabled, but it stays at nagative chance number and slowly crumbles back, allowing only for one pop type to increase for a prolonged time.

You are right. The main problem I had is solved but not the mechanic of this law. When you had the law 10 turns and after removing the law you have to wait another 10 turns to get new population of minor faction, that is very strange and reduce the value of this feature :(

The good solution will be to start again at zero points after removing the "Species Stability Act". The devs have now 2 days time to implement it before new DLC come ;)
