Building Scaffolding Issue

Summary:
Whenever my hearthlings attempt to build a building, they leave the building with the scaffold up and the error message pops up. Happens more frequently when town alert mode is activated during construction.
Steps to reproduce:

  1. Start a building that requires scaffolding
  2. Either leave them to their own or enable town alert.
  3. Disable town alert
  4. Watch the error message pop up…

Expected Results:
The hearthlings should destroy the scaffolding and continue to adding doors and windows.
Actual Results:
They leave the building and idle.

Yes! I’m having the same issue, I didn’t realize town alert was what was triggering it. Somebody said it seems to be an issue with the scaffolding being uneven, I guess when they return to work from town alert mode. I tried destroying the scaffolding using commands and I think that kinda fixed it. Hope that helps :confused: I’m not a very techy person :man_shrugging:
