Spinning wheel cannot always be placed during construction

When I was designing a weaver’s building, I noticed that my Hearthlings refused to finish the building. The only thing still missing was a spinning wheel. I had two spinning wheels available for them. Pausing and continuing the building, and saving/loading/restarting all did not work. I destroyed the building, and used the same building template somewhere else and got the same result, as can be seen here.

Steps to reproduce:

  1. Design a building with the weaver’s workbenches close to each other.
  2. Have your hearthlings try to build it.
  3. Check the spinning wheel and notice how it doesn’t get placed.

Expected Results:
A finished building with everything placed.

Actual Results:
A missing spinning wheel where there should be one.
