Bugs
If you have regular or enchanted versions of the target items, they will be removed from your inventory instead of the stolen ones. For example, when attempting to turn in Garvey's Gold Diamond Ring, it will remain in your inventory and a Gold Diamong Ring that you've enchanted will be removed instead, or Illdi's Sapphire will remain and a regular sapphire will be removed, etc.

-Hafjorg's Flawless Emerald has 0% chance to pickpocket even with item and potion boosts. Pickpocketing is immediate failure and guards are summoned. This is also the case with Helgird in Windhelm and her jeweled necklace. The seem to be no solutions to this bug so far. On PC version.
