Pokémon Sleep has confirmed a display bug affecting the Packed Portions Cooking Week event bonus for the Bulk Up (Cooking Assist S) main skill, which is supposed to increase the number of ingredients gathered by 1.5x. The issue affects the Home screen display, but the developer confirmed that it does not impact game progression and plans to address it in a future update. Separately, a bug that could prevent the game from progressing during Sleep Research under certain conditions has been fixed through a server update, resolving the issue for affected players.
