[CoL] Cows Disappearing from Sheds

It's a related issue, to be sure. When I chose "Purchase Animal..." after encountering the bug I reported on this thread, the shed became occupied, but the animal would not come out. I used Debug to create a cow and only then did the animal emerge normally. I have also run across the "cow stuck in inventory" snafu that others on the forum have described while I was trying to fill a vacancy caused by a disappearing cow.
