Fixed an issue where, under certain special resolutions, the initial letter page could not be closed, preventing the game from continuing. Buildings in the commercial street can now select an already occupied recipe, but this will cause another building using that recipe to stop selling. An additional anti-mistouch feature has been added when retracting farm equipment. Updated some UI elements. Added a new pop-up introduction page about recipe development gameplay (normally triggered during Rose's research storyline and will only trigger once).
