Hi, So I was catching a tentacool and it was already in a pokeball. While it was in a pokeball, I was switching the order of my pokemon. When I was moving my bulbasaur, the tentacool was caught and my bulbasaur dissapeared.
Hey, Luis12335 did you try and re-log? Sometimes the inventory glitches out and re-logging repairs the issue. If not, contact one of the Admins via discord or on here with the issue and they should be able to figure a solution out.
