I had this error as well. I was able to fix it by using the testing cheats and shift clicking on the mailbox to remove the Modern Development N.A.P. then I deleted the wall I had created next to the door. The door that comes in with the Modern Development takes up two spaces where the original only uses one. I then used the shift click to put the Modern Development N.A.P. back into effect after removing the wall and the door was there.

I play on xbox. This is happening to my save as well. I was unable to recover door and was forced to move my family when this occurred. I attempted to repeal the N.A.P. but collected signatures not registering since this enacted in game. I even uninstalled game to see if it would help.
Was this ever resolved? Id love to get my door back.
Also noticing in the apartments here, as well as city, shipping items on plopsy isnt registering on apt. mail boxes.

I just had this issue as well in Stonecrest Apartment 4.I was on the lot, half my household was standing outside the door chatting with an invited sim, the other half were inside. Immediately when the NAP was enacted, the door disappeared. The problem is that the original door is a one tile door and it's replaced with a two tile door. If there is anything next to the door, the new door can't place when the NAP goes into effect if bb.moveobjects isn't already on.

Playing on Xbox series S. This has just happened in my game. I hadn't looked at the completed development so didn't guess the doors and windows would change with the NAP and I had floor to ceiling panelling decor on the wall where the new door was supposed to be placed and a single space door there. So no front door spawned and one window was missing too. I had to exit without saving and move everything away from where the door would go in build mode from manage worlds. Then when I went back into my game and the NAP activated again the door spawned. The window didn't though because there's a very low platform in that room.
If we could edit the exterior it would be much better. In city living apartments with balconies like these we can edit them on the balcony side.
