This may have been already suggested, but if not here goes. Would it be possible to have scaffolding that the hearthlings can’t reach highlight red. Would make it easier to find out which piece is causing the hang up when they are tearing down scaffolding. Majority of the time it’s a ladder that they either tore down scaffolding first and it’s hanging or they built it in the structure itself and can’t get to it. This can happen on the same build I’ve done 20 times but this time they got ahead of themselves and left something hanging.
Just a thought. I strongly dislike the IB command and dread when I have to use it because one little ladder was hiding that I couldn’t see.
