Bug/Issue The model of Alex’s seems strange(SWITCH)

It was autumn(in game) when my player married Alex, he behaved well in the very first a few days: standing in kitchen or his own room, and I could see his ‘face’(front texture) whenever I entered my house.

One day I came back home, I saw Alex kept his ‘back’ to me. I hugged him and he responded by a warm hug too, then he kept keeping his ‘back’ to me when I walked away !! That night and every after night, Alex’s texture in house just left one status: keep his back to me whenever or wherever( in kitchen, or in his gym room ,or even in bed !!!).

Hope you could fix my Alex right.
