I'm not sure which event you are talking about, I'm behind on the game and need to catch up, but some of the scenes in the game once you progress are lost, most you can replay, some you can't.
Thanks, when I first put the time skip in, some people said there was issues, but no one has mentioned any since then. It shouldn't effect the game play at all, I used as much of the original code of the game as I could. From the limited testing I have done it did not effect my game play. The other cheats should not effect game play ever, they are just recalculations of the stats, ex: mood = 100 instead of mood - 15 when you do an event or time advances.
