[FR] 'Not Expanded to OPS' when trying to place roof/Deleting floor on rental

I've been playing the Tiny Town challenge using residential rentals to separate the townies. In my recent build I'm building a warehouse loft kind of house. Anyways I've been trying to delete part of the floor on the second floor and every time I hit it with either the sledge hammer or delete floors I get the "not expanded to ops error". I've rebooted the game, moved the sim out, deleted all the furniture, there is absolutely nothing clipping or in the way. I don't play with any mods or CC. 

I know the residential lots can be buggy but dang this is really annoying 🫠 anyone know how to fix this? 

justabrean It's hard to figure out what the issue is causing that error message without pics of the lot or having the lot to troubleshoot.  I am willing to take a look at the lot if you want me too.  Just upload the lot to the gallery and reply here with the name of the lot and your user id if different from the userid that you use here (justabrean).

Every time I try to place a roof, set a floor by room, I always get a not expanded to ops error and it will not allow me to do whatever it is. I’m trying to do. This just started in the last day or two. 

Update:  I have 4 units on a residential rental lot. I had to remove the stairs from the last 2 units that I created in order to be able for it to work properly. I have not finished to add the stairs back yet. It seems like the stairs were the cause somehow.
