Two-Star Enemies in Ashland During the Day

Me and two friends are playing on an un-modded server and on multiple occasions we have run into two-star warriors and twitchers during daylight hours. Is this normal? I've done ashlands solo and don't recall this ever happening except >!near Dyrnwyn fragment temples!<.

Do the ashlands work differently from other zones, where two-stars are basically nighttime-only spawns?
