In an attempt to access the overgrown ruins the camera shot up high and became almost unrensponsive. This happened right after clicking on the lockpick in my inventory and clicking on the door. I can only move the camera down and to the right with the S and D keys. Horizontal camera pan with the mouse works, as well as zoom. The camera is not above the characters however, and can't seem to reset it. It's a birdseye view of sorts but not looking straight down, rather the "normal" view but really high up. Kind of like a world builders view when wanting to look around.
Edit: After analyzing it more I found out the camera movements with keys only go north and west. It also transcends terrain if high enough.
