[1.3.3066] Animal from trader doesnt leave pen after healed

[Hatti]

1. What the circumstances were.
I was greedy

2. What happened.
I threw 2 pilas at a muffalo from a trader cause i wanted its stuff. Of course i bandaged the poor muff in my pen. After recovering and taking care of it, it wont leave anymore.

3. What you expected to happen.
- Muffalo leaves my pen
- I dont see the wool grow percentage of said muff in my pen

4. Steps we can follow to make the bug appear on our machine. This part is important! We need a set of steps which we can follow to get the same results you're seeing. Ideally you'll test these steps to make sure they work from scratch.

- Create a pen with some free animal spots
- Get Trader with a muffalo
- Throw 2 pilas at muffao to down it
- Take care of muffalo at a free animal spot in the pen
- Let muff heal
- Muffalo wont leave

I am in 1.3.3077 now.  When I follow these steps, I can see wool growth on the muffalo, and when the doors are open it tries to leave and then leaves the map.  I think this is resolved, let me know if you have any issues like this again.
