The game is fun but problematic

I have noticed that when you win a pet from a mission or from completing a collection, if you place the pet out and dont immediately buy a mate for it, the pet will disappear. As in, you will have the play pen, but no pet inside it. And you cant exactly buy the pet again, can you? Please fix this. There are other glitches as well, and the ads upon opening the game are just ridiculous. Please tone those down as well.
