General Updates

• There was a bug that sometimes prevented players from completing number 55 on the Mystery Board. We’ve now fixed this bug, and if you obtain the “Squire’s Memoir” in a bottle, a treasure chest containing the “Caduceus” salvage will correctly appear in the location mentioned in the note.
  • If you have already completed Mystery Board number 55, an open treasure chest will appear. You can still obtain "Caduceus" by salvaging it from other locations, but in that case, Mystery Board number 55 will not be completed.
• The camera direction displayed on the map and the orange circle for biometric signs are now easier to see.
• The orange circle will continue to be displayed for as long as the UML is present.
• Other adjustments and bug fixes have been made to make for a more pleasant gaming experience.
