With the builder stars community event, I decided to track two achievements in one game: the Endless mod achievement and the 18 builder stars achievement.

I had 18 builder stars but no achievement (bur I did get the Endless special achievement when I won ofc). Does the Endless mod forbid achievements? In a broader perspective, are achievements locked when you play with mods? It's just a genuine question: I'm used to Paradox games, so I wouldn't be surprised if it were the case.

Other question: did the builder stars at least count towards the Mississipi event, or were they lost in the void?

The Endless Mod disables all achievements except for the one mod-specific achievement.  I think that the devs said that builder stars count towards the event in a modded game though.

Thanks for the answer! Well, if at least the stars helped the Mississippi event, that's the most important!
