A simple mod to remove all crime bounties when you change your face using the NPC in the Ragged Flagon.
So. You've changed your identity. How is it that the guards in each hold still know exactly who you are when you (in theory) don't even look the same anymore? Well now they won't. After having your face changed, crime bounties in every hold will be removed. You're on your honor though, since the script can't tell how extensive a change you make to your face.
