Revealing mistake: The Alolan variant of the Exeggutor is portrayed as being so tall that its head is usually off screen above the camera, but when bending down for attacks you can still see it's head. If you defeat a gym while using the Alolan Exeggutor however, the victory screen will have it's head cut off much lower down and just disappearing into the void where it could still be seen otherwise.
Revealing mistake: If you equip the Poke Ball Grip pose for your character, and have a buddy Pokemon walking next to you, in the character screen your foot can be inside the Pokemon or leg going through them.
Bug: When viewing your Buddy Pokemon from your character screen, if you spin the Pokemon around or turn him while running your finger down over his candy to go to your stats page for him, sometimes it causes an animation error. Where the Pokemon will be duplicated and standing inside itself at the top, usually in different positions from each other slightly or animations lagging behind on one just barely.
