Hi all *waves* am new to the forum.
Just thought I'd report a small incident that befell my poor dog yesterday; he decided to follow his friend the horse into the stable and take a nap together. The following morning when I let my horse out, the dog was unable to get out.
I tried for ages putting the horse back in and letting it out, to get my dog run out - but to no avail. In desperation (having tried everything, including trying to delete the stable) to save the dog's life, I put him up for adoption. Thankfully, that worked, he was teleported out of the stable and whisked away. I was then able to adopt him back into my household.
So until this little glitch is fixed, if your cat or dog gets stuck in the stable, the only option I found to save it is to put it up for adoption.
