had a dating issue too, after having 3 dates working well ( the initial -restaurant- one, the aquarium and the game area ) the 3rd one i tried ( i think it was the libary one ) it just didnt show up any action/dialog/window and did stay in management mode. After loading older savegames, even the dates which did work before, didnt work anymore. After clicking "invite on a date" it just hits me back on management screen without something happening.
but so far, i love it :D hope its getting fixed soon =)
