Patch 4.2.1 has been released:

• Roguelike mode has been fully translated.
  
• Added an easter egg to Marisa regarding her old friend.
  
• Greatly reduced the difficulty of DLC2's Bizarre Cooking Competition when going through it for the first time. First-time playthroughs should be much easier now. (Rechallenges are untouched for players who want the difficulty.) Also improved some hints.

• Improved the UI display of the "Unable to use the same ingredient for the next X seconds" debuff.
  
• Some special characters in DLC2.5 will now dance differently to the beat.
  
• Added a new requirement to unlocking DLC2.5's chapters.
  
• Max additional time from DLC5's Creator's Box changed to 720
  
• Reisen II's three trials will now show a popup before starting.
  
• Added a new filter option for dishes/drinks on the menu.
  
• Miko and Byakuren have been added into the album.
  
• Optimized text display, reducing overhead.
  
• Improved the hints for DLC5's "Eye of Minute Movement".
  
• In DLC5's survival mode, the requirement for Yuyuko's illusion from Incident Scramble: Inky Blossoms now caps out at 300.
  
• Added hints to the cooking UI.

• Fixed some text display issues.
  
• Fixed the Scarlet Devil Mansion and Bamboo Forest of the Lost not giving recipes that match the player's level exactly.
  
• Fixed other filters being disabled when alphabetical sorting is enabled.
  
• Fixed an issue where immediately clicking on another location after using portal travel on the map would cause you to use up the time required to travel there.
  
• Fixed an issue in survival mode where refreshing trends with money allowed you to overdraft your account.
  
• Fixed an issue where the speed at which menus cyclable by the shoulder buttons (e.g. ingredient gathering) would be off if a should button is held down.
  
• Fixed some UI positions and text overflows.
  
• Improved the spawn location of Reimu's node in the "Truth Behind the Fruit of Desire" storyline. No more continuity errors due to skipping in the shrine.
  
• Looking at dialogue history while a CG is active no longer hides the CG.
  
• Fixed an issue where the submenu of the Mystia's Izakaya options menu would "remember" the place of the mouse when it clicked somewhere else and cause the submenu to briefly move.
  
• Fixed an issue with Aya's spell card in the Korean version.

Have fun!
