Hello!! I am new here so if my style is a bit off then sorry. I was just playing a on a small airport and I was building a staff area on the second floor. I noticed that a little while back you don’t have to build terminal under all second floor; you can just use some 1 by 1 terminal blocks under the cornors of the 2nd floor terminal. I tried that again today (using 1 by 1 blocks on top of the 1st floor and large terminal on the 3rd floor) and I noticed that I can not place any objects or zone the area where there is no terminal underneath third floor. I have not filed a bug report because I do not know if this is intentional.
Just had a play around and your problem is definitely replicable. Strangely enough, the problem doesn’t seem to exist for zoning the second floor with a missing first floor. So I’d assume it’s a bug?
So basically, I’ve tried (using the 1st/2nd/3rd floor naming system):
3rd floor, without 2nd floor, but with 1st floor → zoning problem exists
3rd floor, with 2nd floor, without 1st floor → no zoning problem on either 2nd or 3rd
3rd floor, without 2nd floor, without 1st floor → zoning problem exists
2nd floor, without 1st floor → no zoning problem
