For Rent roofing "Not expanded to ops" error

I'm running into a similar issue with the same error. I am trying to use a fence to add designated outdoor spaces to my townhome apartments (please let me know if there is another way to do this). I create the fenced-in areas and use the interface to assign each area to each apartment, but I get an error when I try to delete the floor to expose the grass. The game still thinks that even as the property owner, my sim doesn't "own" that space, so I can't change it, which is bizarre. My townhouse building is pet-friendly, but the dogs won't go potty because there isn't a space on the lot without grass. The game still views these areas as off-limits. I could deem each backyard a shared space, but that's weird and defeats the purpose of private gardens. Can we have private outdoor spaces with residential rental lots? 

Something strange happened with this lot. After not being able to add the new roof pieces, I gave up on that and went back to Live mode and had my Sim buy the property. My Sim then traveled there and went into build mode and -- there were all of the roof pieces I tried to place. I could tell it was those instantly, based on what I was attempting to get the roofs to work, like copying the piece next to it a lot, expanding that piece, adding different shapes, trying to add roofs on a lower level, etc., they just all appeared! I deleted all of my attempts to place the roof before and then it worked and let me place what I wanted. 

I also had this issue. So I tried the go back in via live mode build instead of map build. Sure enough, all the roof pieces I was trying to drop in map build mode were now visible. Only thing is, I cant shape them to the house. If I try, I get the same "Not expanded to Ops" : (

UPDATE: So after reading some similar issues on other forums with the bug in 2020 on 702 ZenView, the recommended remedy was to delete stairs. 

I unmasked all my rental properties and did the same, deleting all the stairs in the rental properties. Sure enough, I can now drop and alter roofs without getting the "Not expanded to Ops" error. 

If you're getting this error, try deleting stairs on all your properties one by one, and see if it fixes the issue. 

I didn't try in Map build mode. You may have to do it in live build mode for it to work.

If you keep going to manage worlds after you change it each time it’ll load in when you come back. It takes a lot of time but it’s that or delete it. I had this problem when I wanted to use beam foundation next to brick foundation 

I had this error and went around it by moving all of my staircases outside (just randomly) then I could place and edit my roofs. Then I moved the staircase back. 

I have this issue too and I’m on console… not sure why it’s in the mods and cc section.

@lucombre The Game Issues section was split off after this began. We're moving topics when they crop up again. I'll move it over now.

I have been having this issue too. I went onto the landlord's lot to try the stair work around. When I did I noticed all the random roofs that were left from me trying to roof the tenants house. I decided to delete them before the stairs. Before I deleted the last one a checked to see if I could edit it and I could.

Same for me when I return to lot after travelling or logging off the roof pieces are all there I can delete them but I can’t do anything else with them I just get error. Also I am building multiple homes on one lot as a challenge only thing downloaded is the lot itself from Deligracy’s tiny town challenge. I had no issues with the first house build but after I turned on rental lot this issue started with the other 2 homes. I play on ps5 so mods are not the issue.
