I keept running while having the "Lassoing Bug", then found a new animal, automatically entered to the picture mode for this new animal and, due the shutter button was behind the zoo/retry buttons, I pressed retry and the camera view changed. Back to normal after visiting the zoo. Version 1.21.1 from Google Play
