The worldspace is outside, during the day when I've been testing if that changes anything. They also aren't leveled creature spawners, since the project I'm making this for changes the leveling around a lot. So I haven't set up an encounter zone or anything else you might need to do that, and I wouldn't know how to make one even if I did need it.
I really could use an answer fast, since it's the only major issue with the project I haven't been able to solve yet.
