My AI model’s head did a full 360 spin while showing off my dress — what’s going on?!

I was trying to generate a video of a model wearing my product dress, and everything looked great... until her head suddenly did a full 360 spin like something out of a horror movie. 😱
Anyone know why this kind of glitch happens with AI-generated videos?
