No this is not only a visual bug. I was playing showdown on the mobile. What you can see in the first image are 2 garchomp, in vgc 2017, well the garchomp on the left is a *beatiful and fantastic* GASTRODON, but in the second image you can see that there isnt a GASTRODON. Now if it was only a visual bug i would not wrote this here, but, over wat i already Said there is more: you cant hit it. It's not like the attacks miss or things like that, it's like the game doesn't know that the pokemon is there. So if you kill all the 3 enemy's pokemon over that gastrodon you have only the possibility to hit your ally cause its like none is on the other Side! Now, is not the first time i see this, it's like the 25th so please PLEASE, it's becoming frustrating as hell forfeit for that onlyy pokemon!
