[SE] [AA] Getaway Sims don't autonomously"Climb Down" from Rock Climbing

Hi there,

I played through the getaway by assigning Sims as retreat guests to do the rock climbing at Yukimatsu neighbourhood which I found there are 2 climbing points; one with the pathway to go down and the other one (in the screenshot) without. So other sims that I don't control stuck at that area. The only way to get out of this spot is to "Climb Down" but they won't autonomously climb down after they autonomously and successfully climbed up. 

Need advice. Is there any possible way to make them autonomously climb down? Or is there any cheat or mod for workaround?

Thanks very much!
