Treasure hunt at the castle bug? 2/3 chests

[etmaemusic]

I already have the 3 endings first, I'm trying to do the secondary missions, specifically the treasure hunt at the castle , however I can only open two chests, because I opened one before this out of curiosity but now I can't do the mission Because it appears to me as already open, specifically the chest that is almost at the entrance of the castle, does anyone know how I can open it again or should I play the game again to that part?

It is strange because when you open them, before accepting the quest, the chest is closed by the character you are playing saying there is nothing useful.
As long as you are opening the right chest. in case you are, buy the chip that scans the objects present so you can see them in the map. available in the run with 9s after the main part of the desert I think, from the chip seller of the resistence's camp.
in case you have already finished the game try using chapter selection and go to just before the quest, so you can accept it again

Wrong chest most likely. If you open of the 3 chests early, the character indeed says "nope nothing useful here" and closes it. This is the chest closest to the entrance / the first one you can reach.
