Personally I'm fairly new to the game, and im playing on settings that are effectively default. I have a well lit area around my home but im still having rifts pop up extremely close by and dump enemies out all night. seems like wherever i go there is constant rifts. the only real break i've had was a night on 'low' activity when nothing was spawning nearby. nearly raged out fighting some 10 drifters and 2 crawly-sprint dudes. 10 re-spawns later its finally getting light out
