I played Fallout 4 extensively for about 300 hours and reinstalled according to the automatic instructions for this Mod. I hope I did it properly.

However, I noticed there is no control for me to Sneak. When I go Settings, the option to set the control for that is just ... missing. The strange thing is, I thought I saw it last night and attempted to change it, and then it disappeared. However, it was 4am my time, so maybe I was just seeing things.

Anyway, appreciate any guidance how to get that back, what I'm missing, or how to go around it via console commands or something.
