Bugs spawn on qr paths just the same.
I am not a fan of overly hacked towns. With a ridiculous amount of trees and stuff you can't even navigate through it. I usually like to at least head to the edge of the cliff or river if I'm lost and since they often put trees along the edges I have a hard time navigating. Some hacked towns have been nicely done though. I also don't like when the clothes are wrapped. I want to just look at what I want to wear and put it on right away lol.
I lay patterns down when plot resetting, and had them down for 4 weeks.
Never saw one bug until I removed them.
Also fruit vanishes on patterns.
