Tower not being built - Develop 3002

Summary:
My Hearthlings Refuses to Build this Tower at random times they seem to stop tried on two different saves just to see and they never finish it on either of them. I seen this on a few other building before but i start with this one.

Steps to reproduce:

  1. Put out my template on a world
  2. Put hearthlings to build it

Expected Results:
Building being built and scaffolding removed
Actual Results:
Left unfinished with parts missing and random the times i tried it where they stop building
Notes:
I have a few mods but those only add more crafts and i do not use any of these mods in this building this all original parts of the core game.

If you have a error message about scaffolding when reloading the save when this problem occurs then the problem is that the game doesn’t understand that it needs to update the scafolds after a new part of the building is completed. This bug is discussed in another topic, so you should check that out.
