Engine errors in building menu

Sooooo I was attempting to build a castle and i kept getting engine errors… most of which i just closed and ignored until about the 8th one I finally copied to list on here. Im not really sure what triggered any of them as they all seemed to randomly happen while in the building menu and after the building was finished.

Steps to reproduce:

  1. build large (25x45) two story building?
  2. ?
  3. ?

Expected Results:
a finished building with a full roof and no errors
Actual Results:
one of the four towers would not allow for a roof and lots of engine errors
I only copied the last error i had which was 5 pages long but there were roughly 7 errors prior. I was unable to save the building as a template so i used the console command “ib” to build.
