Unfortunately, my character was then stuck in Sneak mode in first-person, with a broken hybrid cursor that was both the regular mode crosshair, and a big open eye to show that I was 'detected' (there was no one else in the house, but I think it showed 'detected' because I wasn't actually sneaking). In third-person mode, I appeared to be standing errect. When I moved in third-person, I was moving at full-speed ... in first-person, the camera was notably lower to the ground and I was moving at sneak speed. No amount of button clicking would make my toon change his posture in either third- or first-person view.
Here's the kicker: reloading old games doesn't reset the bug. It imports the condition into whatever save game I pull up ... if I was standing in the old game, I am permanently standing. If I was crouching, I am unable to stand up. My posture mode simply cannot be changed.
I am using a gamepad, but playing on the PC. I am going to try moving to Keyboard and Mouse to see if this corrects anything, but I am skeptical. Has anyone else encounter this bug? Any solutions, or ideas?
