So I have no previous save data for this character, he's far into the game... My pipboy is invisble, but the key guide shows. I can't use shift to sprint either. My limbs are all healed. No rads. Everything else seems normal.

"What a twist!"

It does work however IF I am in power armor. Otherwise my pipboy won't display right. Sprint can only happen if I'm in armor too.

What can i do?

Do you have any mods enabled? Sending you a message to get some more info. Thanks!
