Just as the title says I'm unable to preform a sneak roll (Yes I have the perk) in First-person over and over ie holding down LB but when in third person I have no problem. Any ideas on what's happening?

It happened to me too, but I just loaded an earlier save and it fixed itself. I have no idea what the cause was.

It's weird because it works in third-person even though it doesn't in First and yeah you're right reloading works fine I'm kind of just wondering why it happens.
