That’s the strange thing, @Sweeck , and is something I’m looking into at the moment.
This morning I did a different test where I order a Carpenter to make items, and while he was working on that task, I saved and reloaded that save a minute later, and what would normally cause the lobotomy bug wouldn’t do anything. Which is why it seems as though it doesn’t actually cause a problem until the next real life day of that save.
