Managed to give my Blissey golden berry at the same time when someone knocked it down and got the 2 coins and had it on my knocked down Pokémon list waiting for a revive.
Same blissey defending on two gyms simultaneously.
My defending Pokémon list didn't show it on there either, but it still remains on the gym and seems to behave like normal otherwise.
However i purposely took down another gym so I could see and i was able to place it in the another gym too.
On the video i show the Pokémon on the new gym and then on the old gym at the same time and open my storage and show that i indeed only have that one blissey with the "Blissey96%' nickname.
So was it because of the frame perfect golden berry from either from me or my other friend, or was it because of the raid hour started here at the same time too?
Too bad that I don't have a car, i would honestly be interested to see if I could place 21 Pokémon in the gym at the same time because of this bug. Even though normal top limit is 20 Pokémon.
I mean I'm not interested in cheating the system or something, just here to report that Pokémon go indeed is very very BÖRKEN game. 🤣
