Soak for a Long Time in a Hot Spring

[Manderley]

Has anyone successfully completed this aspiration goal under Mt. Komorebi Sightseer?  Every time I send a sim to relax in the hot springs they immediately get out to go kick the soccer ball.  Is there some trick to it?

Mine stay in. Maybe test it out by turning autonomy off? Or queuing up actions with other sims in the hot spring.

Mine stayed in the first time until he got the moodlet required, but he got up the second time (to my surprise). I had and still have autonomy off, so I can't tell what makes a Sim stay put or not. It might be a bug? There were other Sims in both times. But I've noticed that autonomy doesn't always work in some situations in this blasted game.

Update:
It would seem your Sim can get the necessary moodlet for the challenge even though getting up. Just keep forcing them to get it.
