There are times when I enter the TARDIS from outside that a nearby deer, rabbit and even once a dragon ended up inside the flight chamber. The dragon's head and neck protruded inside but fortunately didn't attack. They all went away eventually but now Belethor wandered in from inside his shop and has been in my TARDIS ever since. Is this a bug or what? If so, how do I extradite Belethor and get him back in the shop where he belongs?
