@crinrict The screen shots are from an active world I've been playing recently. The save I sent was a brand-new world created just for that. Never played before then. I've had the problem on many worlds for quite some time. I clear caches periodically, and that save was created with absolutely no mods installed whatsoever.
I'm not sure what's triggering it. Before that save, I tried it in the next-door house and I couldn't get it to fail. I tried it in that house and it failed right away. But it's not just that house as you've seen.
That save was in Willow Creek, the original unmodified house. I've had the problem in every neighborhood. The screen-shots were in the house in Brindleton Bay, Bedlington Boathouse that I modified.
