Building won't fully build / mobs spawning in housing

Tried to build an epic castle to find out i couldn’t. Also keep getting mobs spawning inside buildings/ on top of foundations. (not sure if it is a bug, but if its not maybe it needs to be changed?)
Steps to reproduce:

  1. click the unmade parts
  2. do the build command (poof 2 errors)
  3. wait for a mob to spawn
  4. usually spawns in building or on objects put down

Expected Results:
building to be built
no mobs indoors
Actual Results:
building missing parts
mobs spawning in my safeish zones
building might have been too epic

No worries. The Discourse software will not allow uploads over 10 MB, and we can’t change that. Uploading to an external site the Google Drive is our usual recommendation.
