I am surprised that I can't find mention of this anywhere online, given the content has existed in this state for several years, however there is a very frustrating and somewhat gamebreaking bug when challenging the battle arena in Hoenn Battle Frontier (and the same bug exists at the set KO battle tent).
Currently, if your Pokemon loses the points based decision after 3 turns without a KO, they will be removed from your party completely and not return for the next battle if you win, meaning that you will have the face the next 6 or less battles of the round with only 2 Pokemon in your party. If this happens again you will then have only 1 Pokemon in your party.
Has this not been discussed at any point before? I'm aware many features from some regions will never be implemented, but surely a feature that is just broken would be fixed? Are there any plans or have there been any attempts to address this?
