Haha. Yeah, again, sorry about the long post! Thanks so much for answering all my questions!
I've updated several times in the last few days. I believe I updated to the latest version a few hours after you posted it, so all the things I mentioned (like the livestock issue) apply to this version (I think it's 0.18.4?). To clarify, I am able to walk through chickens/geese, and I've seen my pig and cow walk through each other. Related, I've also noticed that if I walk in front of the pig, causing him to have to stop, he will sometimes start spinning rapidly back and forth. This doesn't stop until I leave the barn.
As far as saving, I understand your concern. Even saving every 12 hours instead of 24 would help, though. There's a lot of progress you can make/lose in 24 in-game hours. I had to go back and re-mine a hundred or so ore, turn in a quest again, and repurchase 5 or 6 pieces of furniture. This was today that that happened.
Thanks for taking our feedback into consideration. I'm excited to see how everything develops!
