Kagha's Chest is now been given the status Lockpicking: Impossible. Even with 16 Dex, proficiency in Thieve's Tools, with lockpicks in inventory the Lockpicking option is greyed out with the impossible status.
You can't open the chest even if you pickpocket Kagha's key off of Kagha. Which should open the chest.
The only way to get the contents inside the chest is to do 50 points of damage to the chest.
I do not know if this is an intended change or a bug but if it is intended the quest that is available from the note inside the chest will be started by incredibly few players.
