I'm noticing recently that quite often when I press my sprint key, nothing happens and I have to release it and press it again in order to activate sprint. At first I thought I had a hardware issue with my keyboard, but after some testing I realized that the game does in fact recognize I have the shift key held (ie. if I press enter and start typing it's all caps), but sprint is not being activated until I release it and press it again. It's happening most frequently after combat and/or looting. I'll press and hold sprint and nothing will happen until I release it and press it again. It's not every time, but it's often enough to be very annoying.
