A game-breaking bug has been patched in Pokemon Mystery Dungeon: Rescue Team DX.
Nintendo has released an update for Pokemon Mystery Dungeon: Rescue Team DX, and you will want to apply it to your game in order to fix a game-breaking bug.
According to the update notes (via Perfectly Nintendo), a glitch occurs in dungeons with a fixed party when the player and their partner are defeated in the dungeon and you remove the third Pokemon from your team.
Nintendo said to avoid the issue, don't remove the third party member, however, if you did and can no longer play, the update will fix it so you can continue to play.
The game was released on March 6, and if you're just picking it up, here's some information on starter Pokemon, personality quiz answers and buddy Pokemon. If you are wondering how to evolve your Pokemon in the game, we have that covered too.
