Met a new player (@sir-jack) and was showing him around. After trading, my view got stuck facing him. Couldn't move, couldn't pivot away without springing back to that view, and couldn't teleport away to the Sanctum. It acted like a disconnect, but when I logged out and back in, the server said I was already connected and to try again in a few minutes. I'm using those minutes to type this.
We were underground a ways in one of my mining areas, in case that makes a difference.
