That's a tricky one. Since you can move around, there shouldn't be any issues with the build and we haven't had a similar issue before. I would check the mouse input again.
Same here. I can move at first, but while I'm hiding behind a wall while in scoping, I moved a little bit and I got off from scoping. After that, I can't turn to the left, only to the right. Also, when you scope, it's not the point what I was expecting to view.
