• Expected Behavior: To not unlock steam achievement/ De ne pas débloquer les succès steam qui ne sont pas dans ma difficulté

I played a game of 275 rounds in metropolis difficulty, my map was personalized since I set its size to immense without changing the number of AIs or other factors. I also think I had some other bug like no oil on my map.

At the end of my game on Metropolitan Difficulty, I unlocked the Steam Achievements for Metropolis, Nation and Humankind Difficulties (I'm not going to complain I prefer to keep them). But this is still a bug since I have never started a game in this difficulty.

Same for me playing Nation level, it unlocks Nation, Metropolis and Humankind achievements (think it should work the other way around, difficulty Humankind unlocks all achievements etc.).
