Recently I wanted to design and build up an own designed house, but after a while my hearthlings just stopped working on it. I thought it would be something like a bug, I designed somethind wrong or any other error would stop them from building.
But in the end I found out it was way simpler:
A placed storage box stood next to the outer wall, and thatswhy my hearthlings couldnt build up a ladder which they needed right there. So they just did nothing (even tho they could have worked on another part of the house right then).
I think it would be great to mark objects which are blocking the house building progress (or anything similiar), so the player can see and interact immediately.
It is a simple feature but could prevent some frustration
. I was simply letting you know that your idea is a common one and the devs would like to do something with it in the future! Right now the suggestions category is a bit overwhelming (over 1000 topics), and we are gearing up to do some mass organization, but it has not happened yet.
