THIS IS A SERIOUS GLITCH IN THE GAME. IF YOU CLICK ON A BRO MON, THEN LEAVE THE TAB, THE GAME SEES THAT YOU DONT HAVE THE BATTLE OPEN, AND THE BRO MON ISNT IN YOUR INVENTORY. IT WILL THEN SPAWN ANOTHER, LOWER LEVEL BROMON WITHIN A MINUTE AS A SYMPATHY GIFT TO STOP PEOPLE FROM RAGE QUITTING
Please fix this @sweezy it is a very active exploit
