Eh, probably a design decision. They have made many other minor or trivial changes that don't necessarily have an obvious reason.
Nah I don't think it is intended, because there is another NPC called "Kaldani" who is also permanently stuck sitting on a chair.
She is supposed to go to Kanon's corpse and bury him, but she is permanently stuck sitting in front of the campfire so the encounter never plays and Kanon doesn't get buried. Only by moving the chair from underneath her does she do what she is supposed to.
Thanks! I was wondering why Kanon's body was sitting around moldering...
Given that, yes it seems buggy. Here's another instance: Once Cyrel sits down in a chair in the toll house, she doesn't move thereafter. It's also a position such that you can't sneak up on her, so I thought it was an anti-theft measure. I trashed the chair and she wanders around like normal now.
It sounds like they messed up the 'seat nearby' character script.
