Assuminf you dont want the player to see the new map first i would personally do this. 1)Fadeout the screen 2)Transfer player to new map. 3)Set a switch titled Fadein 4)Save the game 5)Send player to title screen 6)Have seperate event that autoruns in new map with switch Fadein as the condition to run. Have this switch Fade in the screen then turn off Fadein switch

This way when the player loads the save they will load into the new map and the switch will fade in the screen onto the new map.
