Hi! I'm set events frequency to 1 day, and probability of each type of event to 80, for testing purpose.
Starting a new game and just wait, without base building.

some times i'm get message like "you hear roars approaching your base", but nothing happens.

playing with Space Exploration mod and Bob Enemies mod. Any suggestions how to fix it?

Same result with all mod off

I will check this when vacation is over. But most events require a built base

It also requires game enemy evolution.
