Playing on the latest alpha release (24.10) and after starting two different games, neither has had any Daily Updates show up over the course of several days. I far exceed the requirements for new Hearthlings, and I’m nowhere near the adjustable limit. Unfortunately, I’ve deleted those two saves but am going to start a new one and will get back if a file is needed or if there’s a change.
EDIT:
Yup, of course, after I report it as a bug I’m now getting daily updates again - not sure what the problem was, but it might still be out there somewhere.
