[Build 144] Auto build walls Causing Bug

Title:
Bug: auto build walls causing other bugs

Summary:
When building a building close to another building, using auto complete walls will allow you to
designate walls where they should not be allowed to go.

Steps to reproduce:

  1. build a building
  2. when building is finished designate a floor withing the 2block buffer around the house
  3. use autocomplete walls on floor, not that the wall drawing tool will not allow wall placement around the whole floor
  4. villegers will refuse to finish house

Expected Results:
ither not able to place floor/walls within the area, or autocomplete not placing walls in that zone

Actual Results:
unfinished houses
