The option for investigating her, ya, had also been hitting that every time point for at least half the days in the week (whenever I came home after walking around, I would also hit this to see if we needed to use that to find her walking around), she was never home/responded.
I recovered and older version of the game, and after trying it the investigate worked there.
So, got it working on 0.21.2 build
After failing to on my 0.21.6a build
And now new 0.22.1 build is out, no idea for it here.
