@AlHollandiyah Back to another new game for a few more tests. Will my Sim get any frequent flyer points for this? xD
The good news is all of her career and social gold unlocks stayed with her in the new game after going through the Replace from Merge Household process in CAS. Same for all of her aspirations, reward traits, and reward points.
All of her collection stats did reset. Not too surprising as I've seen these stats reset just from switching households in the same save! I tried importing her directly from my Library without doing the Replace from Merge Household part in CAS and it didn't make any difference. So we seem to be stuck with losing Collection stats even if we are able to completely skip CAS at the start of a new game.
I know all that is getting a little off topic from the original post but I just wanted to test and clarify these things since the questions were asked. For all of the other reasons you listed I do agree it would be great if we had the option to skip CAS at the start of a new game.
