I put some of my dead animals from the terrible plague before the patch inside of 4 slot sled.
A male pig, male goat, and female goat, all fully grown.
Now when I try to remove the female goat, I can't. I just walk to the sled and nothing happens. The rest of the animals can be removed.
I'm not sure if this is some kind of freak accident or if all female goats get stuck. I'm afraid I only have one female goat and cant sacrifice her to the bug god.
