I've just attempted to post a bug report (for some reason it's not posted - there was a 'preview' button on the form but that didn't convert to a 'submit' button, so I couldn't send).
I'm seeing a 'cannot build outside owned area' error on lots the currently active sim owns. I this morning, I built six properties on a lot, then I had a Sim purchase the lot. Went into edit via live mode build mode and received the error.
Just now I had the same Sim purchase an empty lot (1 Rippling Flats, if it matters) as a rental lot. Went to build via live mode. Put down one flat square tile. Attempted to place another next to it, got the error. However, if I leave a 1 square - or more - gap between tiles, they'll place, but I receive the error if I attempt to place them so they join up (see screenshot).
Playing on a Mac, running Sonoma 14.1.2. Have everything, bar Horse Ranch and a few kits. I've never had any CC or mods installed/running. Game version is

This was supposed to be my 'dream' EP; I've been wishing and wishing for multi-build/occupancy lots since forever. It's not quite perfect (still no lifts, and only 4 storeys) but it's a start.
And FINALLY we have kettles! And radiators! Now all we need is front doors with functioning UK-style letterboxes!
