I've been getting a strange issue but I'm not sure if it's lag or not - sometimes, randomly, my character will just keep running in the same direction for a second or two after I let go of the left stick on the gamepad, and I can't stop him. Or the camera will continue to rotate for a second after I have let go of the right stick on the gamepad. Perhaps it's the gamepad, but the issue started right around the time of the patch.

My girlfriend, in the same house / network has been getting a terrible rubber banding effect in dungeons since the patch, but I haven't at all on my PC. The players seem to update position correctly on her PC every second or so, but there's no animation in between, so again I wonder if it's network connection related lag or something to go with the PC (like it can't work out the paths to animate along quickly enough under certain conditions).
