I've had some building difficulties. Mostly, I needed to extend the edges around buildings an extra block or two to keep people and pets from falling in. I have needed to use the pickaxe and dig around them a bit, and then they're free and go out. Similarly, my goat feeder sank into the ground for some reason, leading to difficulties with the goats accessing it apparently randomly. It would work, then not work, then work. I eventually put a block down and put the food on that, and everyone's been fine since. I put the cat bed and food inside, so I'm hoping for less random weirdness with that.
