It didn't work I don't know what could be the problem. I checked the save I made before I ended the day and there was the {"code":"caliproposal","duration":1} . I tried to added back in my next day save file but still didnt work (I had to add some extra to the starting maid sex event so it doesnt overlap but it did delay that event but the cali event didnt come up) and I even tried to delay emily's event but evn though it delayed it the Cali event still didn't trigger. On a side note I noticed that there was the caliparentsdie event still there even though I completed the quest, though when I deleted it didnt make a difference.
PS: So I was wondering does Cali's event really matter or it just for the CG which will be stored in the gallery?
