Hearthlings can't scaffold when building Jetties on houses

Summary:
Hearthlings first place 2 lots of scaffolding on the same tiles and then when come to take the scaffolding down ignore the first lot they put up…

Steps to reproduce:

  1. build a 2 story house with a Jetty (the first floor is lager than the ground)

Expected Results:
not to put scaffolding over scaffolding/ use the scaffolding that is already there.
Actual Results:
They build 2 lots of scaffolding and then don’t tear down the first set
Notes:

Attachments:
The lighter scaffolding is where the 2 sets are clipping each other.


It clearly needs the rest of the scaffolding taking down.

Was unsure whether to put this in the templates that don’t build cause it builds.
