Can't finish the Sword of Sheba quest, chest is unopenable

I need one more fragment to complete the sword, but the chest at the Rattay blacksmith is unopenable (as on the screenshot). I have no interaction with it. I removed all mods, reloaded previous saves but no changes.

How to fix it ?

save game quit game and again load… its help in 99%

Unfortunately, issue still persist.

You dont need this chest, its broken from first game release nothing inside, pieces of sword are elsewhere…

For ratty top blacksmith is piece at ground level, in room where foods is stored, on top shelf at the left - its small - 10 inches or something like that.

There are three pieces of the sword in Rattay, Pickman, weaposmith and blacksmith. I think he is talking about weaponsmith piece.

In weaponsmith house are not bugged chests… In top blacksmiths are 2 bugged chests.

Do you have the piece from Pickman? Because otherwise if this piece is bugged you can go searching for another one (there are 6 pieces in total).

Yes I got Pickman. I also got Sasau, Ledetchko and Talmberg. About the chest, I was talking the one at weaponsmith this one : http://static.gosunoob.com/img/1/2018/02/kingdom-come-deliverance-rattay-sheba-sword-piece.jpg

If this chest is buggy you can find another piece in Rattay in the house of the blacksmith as suggested in the post above by ruthan.
