So i have this mod on and changed the peacetime to 2000 minutes at start of the game. now it seem like the enemies never attack me. new faction still spawn but doesnt confine to the direction that i set in the mod. weird.

im on 2.1.20 experimental version on steam.

There are no attacks during peaceful mode. That is by design. You told the biters not to attack, yet you're unhappy that they're doing exactly that?
Either wait for the 2,000 minutes to elapse, or change the duration of the peace period by accessing the start menu via the player settings.

well im implying did i pass 2000 minutes and mod didnt active. it been 40 hours and they still didnt attack/

In that case, try changing the duration of the truce.
Also, I hope the biters have a path to your base. I also hope you haven't set a condition based on the evolution level; otherwise, the planet's evolution must exceed the specified value.
