I think it might be worth noting that I’m using a handful of mods, one mod (I believe it’s Cataclysm++?) might be doing something, but beyond that one, none of the others should be affecting monsters in any way. Also, my issue is just with monsters. I’ve not had a single issue with zombies spawning in my home area.
In case you’re curious I’ve had a Mi-go, kreck, flaming eye, flying horror, and that white blob monster spawn while I’m crafting, cooking, reading, sleeping - just everything.
As for the artifact idea, I know I said I didn’t have any artifacts, but now I’m thinking that my biological sword/rifle might have an effect like one (one of the modded items from Cat++), but all I could find on them was that they lowered certain stats and raised others with use, growing worse over time. I hadn’t used a teleporter prior to when the monsters started to appear so that’s a bust, but I could have gotten a stare from a flaming eye, can’t really remember, but do you know how long the effect would last? My character currently is nowhere near my home base so I can’t exactly try anything, but I’ll see if the effect doesn’t go away after a few weeks.
Oh, and thanks for the advice for luring zombies, never thought of burning a house down to make a lot of noise.
