sims 4 map sun myshuno problem

Hi norekiut29​ 

• Do you have two San Mysuhonos ?
• Did you build any r-rentals in this world ?
• Are you using mods/cc ?

no. i just finished install city living expansion pack from EA app. and only play 1 loaded game. 
no use any mods or cc..

Since you just installed it try the following

• Create a backup of your save game
• Start the game and go to Pack Selection
• Disable City Living
• Restart the game
• Start your save. You'll get a warning about missing packs. Ignore that
• Save the game under a new name
• Exit to mainmenu and turn City Living back on
• Restart the game.
• Start your save.
• Check if it works now.
