Re: Midlife crisis checklist not visible during midlife crisis.

After reading around I realized that in my particular case this is maybe "working as intended" but is not clear based on the in-game text.

Sims can have an "early mid life crisis" that will later turn into a "full" mid-life crisis. It is only when a sim enters "full" mid-life crisis mode that they get the checklist. If your sim's moodlets say "early mid-life crisis" it may be 24-48h before the game enters a state where they are assigned a "bucket list" in the Aspirations panel. This was confusing to me, because it is not really clear what you should do when your sim gets the "early mid-life crisis" moodlet and I'm still not sure whether there are any actions to take at this early stage.

So far, 100% of my sims' "early mid life crisis" bubbles have converted to a full mid-life crisis, but I don't know whether this is always the case.
