Is this a vanilla bug (NPCs standing still like mannequins in the middle of benches/chairs)?

Hi, I've been seeing this in a few places while setting up my load order. I know that I've seen it happen at Winterstone Castle and around The Silver Anvil (player home and added inn)...can't remember if it's happened at vanilla locations, but it's a bit freaky.

Basically, here and there I'll see NPCs standing perfectly still like mannequins, clipping through a bench or chair. They react to you with their head and voice...you can talk to them and interact with them, but their bodies are totally still and unnatural looking, and run straight through the inanimate object.

If you wait a few moments, they'll eventually move or sit down on the bench and chair, but is there a reason it's happening and is there a way I can fix it?

The third image shows the same person from the second screenshot a few seconds later where she suddenly snapped back to life and sat down properly.

Any advice would be appreciated because it's extremely creepy XD

Thanks!

In case anyone else runs into this problem, for some insane reason the bug was being caused by a custom race. No idea why or how it could affect regular NPCs but after a ridiculous amount of testing, that seems to be the culprit :-\
