While trying to reproduce a crash bug, I came across this.
To get this, knock out a T-Shape floor, add walls and set your roof to 8 levels before adding it. Now reduce the roof to 2 levels and the extra bits of wall will stay.
Trying to actually build it will cause an endless supply of errors when your villagers try to build wall blocks in the same place as your roof blocks though.
Ah, ladder engineering. I imagine we’ll have to use ladders to finish things for quite a while. There is good news, however: ladder engineering’s importance seems to have gotten lower for slab and/or multi-story buildings, and I imagine future alphas will decrease the amount of ladders that have to be used further. Still, I don’t know why you need ladders for a single-story building - a scaffolding bug, perhaps?
this is a problem with edges being bigger on top or bottom or both, Right now hearthling will not scaff inside the build. you have to use ladders to help finish the build. ie: look at ur pics as you can see they finished the 3rd from the left, that’s cause nothing sticks out on 2 sides, but the others all have tops or bottoms that stick out. Just so you understand. They havent done the script on the Ai to let them build from the inside up to outer edge. Hope this helps you understand why it is happening
