Okay, today I played my Scenario save for about two, very short game days. I forgot that with only one Sim in the household the time speeds up while he's in the rabbit hole known as 'work'. Then I tried to play my ancestral game, but that, too, fell flat. I decided, since I've been told that with aging off, the babies won't age up, that I will go ahead and continue on with Erik and company. I made a copy of the save and placed it in a folder on my desktop, should the worst case scenario wreck the game. I have a backup.
I am now going to play my New Main Save RESET game. When the infants drop, I'll likely roll back and replay Jamison and then the twins. I will try very hard, this time, to just jot up the antics of this new life-stage, as an addendum to the over all life of my Rock Star. Once it's time for their third pregnancy to happen, I will turn aging back on and go from there forward.
I know I had high hopes this would work out with the FLASHBACK save, but I now have more experience. (Yeah, it's me talking. LOL) Wish me luck. The worst that could happen is that I simply continue on with this newer version of the RESET save. But, it will likely allow me to have fun again, and perhaps, curb the stress I'm feeling.
