Ideas
I have to admit, this is the first time that game has been basically unplayable for me. For some reason, if I go into build mode, I can only place or delete one item. If I then try to place or delete a second item, my cursor will pick it up and then I'll be stuck with it, unable to either place it or delete it. Build mode is only functioning normally for the first item I select or pick up, and then bugs out on any subsequent item, until I leave build mode and go back to live mode to "reset" it. The same thing happens with the bulldoze tool, which means that when playing with an active household, I have to constantly click back to live mode, then back to build mode, place or delete a second item, back to live mode, then back to build mode, place or delete a third item, and repeat. Which means clicking back and forth between live mode and build mode for every single piece of furniture, square of carpet, or wall segment.
When trying to do it from the map solely in build mode with a community lot, I just get stuck completely and can't even do it one at a time, because once I've placed or deleted an initial item, there's then no way to change anything else since there's no live mode to be able to click away and "reset" it; basically, it's now impossible to build. It also seems to be impossible to bulldoze a lot. Nothing happens when I click to bulldoze.
