The "Running man" bug

I have noticed this animation bug where my character wakes up with his arms stretched out, as if he is holding a cart, or doing the “running man” dance move.

How it happened:
Use computer and skip time repeatably, going to bed afterwards and skipping time.
(Not sure if this triggered the event)

I didn’t even use a cart during this particular game session.

He is stucked in that position, even after using a computer, car, scooter and many other interactions.

Temporary fix:
Save game and restart

I will take further notes, when it happens again.
