[CoL] Cows Disappearing from Sheds

I haven't had this specifically, but every time a chook shed gets put in household inventory, any hens that are inside it are deleted. This has happened when I moved lot, as the hens were all in bed in the middle of the night, but also when I was just rearranging fences and a chook shed got automatically moved to household inventory - three hens survived and the rest vanished from existence.

I don't know if it's related to the way, when you move house, all the contents of the fridge, bookshelves, toy boxes, and other storage items are deleted. It's very annoying having to empty every such storage into personal inventories before moving house. I probably should have realised that my hens would be deleted too when I moved house, but sadly I didn't make that connection, and had to cheat code the money to pay for a replacement flock.
