LadyAriancia here is another good tip: you can have playable sims aging turned on while non-playable sims aging turned off, so that your complicated world outside the lot is not affected by aging. As I said in the previous comment, once you moved into a lot where there is no other sim (you might want some starting furniture to complete a child aspiration, like the painting one is doable without going outside), the outside world and your main lot are not affected, because they are not loaded and all non-playable sims aging turned off. You can test that to see if "have a child complete aspiration" checks with the steps above in previous comment.
LadyAriancia you can create a backup of your world: https://sims4.crinrict.com/eng/2014/09/backups/
and restore them after using the steps I said above.
Furthermore, the 2nd way, you can play the steps I said above, and don't save. You can "exit your world" without clicking the save option if the aspiration doesn't check. If the aspiration checks, you can select "save and exit world"
What part of, I did my duty and if you want any further tests done you have to do them yourself, in your own game, didn't you understand?
Stop telling me what to do with my savefile, and stop assuming you know what will and will not affect my rules and the way I play. Stop trying to come up with ways to "protect" my savefile while doing tests I in no way said I wanted to do.
