[NEEDS INPUT] Walls that adjoin roofs broken

@gizmorgan Hello! I have just tested in my game and I can confirm that this is what I see:

• If the roof from the first floor only goes to the following max height, the outside wall covering from that roofing does not override the room's wall covering where they intersect:
  
• However, if that roofing from the first floor is raised any further, the outside wall covering from that roofing does then override the room's wall covering where they intersect:
  
• Furthermore, if you raise that roof to an even higher pitch, an open area is created on the two sides of that two tile intersection:
  

Personally, I would consider this a bug or oversight in design. This would make certain types of designs that involve roofing with a high pitch unworkable. 

I have never had Mods or CC in my game, I own all packs, and my game is fully updated/patched. I'm on a Mac.

Yeah, I see this too. The lighting isn't right either. The exposed gable end above a floor will light up or not depending on whether the room below has lights. This shouldn't happen if these is a floor cutting off the light source:

Lights removed:

The roof tool seems smoother to me since the September patch but the gable end shouldn't override the internal wall, which is what seems to now happen:

And yep, horrible things are happening when you raise the pitch of the roof:

Please can you provide more information about your Macs. Instructions on how to do so and what to provide here - http://answers.ea.com/t5/The-Sims-Mac/READ-FIRST-Sims-4-Mac-Help-Guides-and-Troubleshooting/m-p/4612396/highlight/true#M162

I'm also on a Mac.

Yes this is exactly what it looks like to me as well, I've included some screenshots of my game in my original post!

I am on MacBook Air OS Catalina, version 10.15.6.

Processor: 1.8 GHz Dual-Core Intel Core i5

Memory: 8GB 1600 MHz DDR3

Graphics: Intel HD Graphics 6000 1636 MB

I'm playing the regular version of the Sims (Not legacy edition) and all mods have been removed

Ok, I've tested this twice with different results.

The first time, I did it in my existing build and test save and I could not make it happen.  But after seeing @SheriGR and @Bluebellflora posts, I tested it again and was able to get it to happen with both gable and half hip roofs. 

The second time, I created a brand new Sims 4 folder and then it showed up.  I also deleted the localthumbcache file in the Build and Test save and then it happened there too.  Interestingly enough, it does not happen on the gable roof if you use a single roof that goes through the upstairs room but it does happen if you use two room sections, one on either side of the room.  I also found that if you brought the roof into the room 1 tile, it didn't happen but there is no gable end on that end of the roof then.  

Btw, I play on a Win10 PC so this is not just happening on Macs.

Hope this helps.
