I have a few problems when fighting either trainers or wild pokemons. First, my health does not update when i am being attacked but instead my ennemy health goes to where my health should be at. Secondly, when I switch pokemon the ennemy switches to mine and I end up fighting my own pokemon. This bug also causes me to never be able to come back to my original pokemon. I manage to encounter situation were I can not use any of my abilyties and I am force to either run or let all my pokemos die.

I would love to have some help on the matter

I love this game, and I too am having this bug. I came back after 6 months maybe? It is overwelming. Any battle I enter seems to be just what is said by OP. It could have to do with my account being legacy, not this one, my other one, merged to this, so I always appear as this name on forums. Could also be due to a combo glitch I don't know of, like using kings rock with skill link, etc or something. I'm interested to know aswell. Game unplayable like this.
