Steps:

I was playing the main story line, and finally got to a quest called Rock Solid Protection. I am doing all these quest with a friend, so I know I am not missing anything, We did the dungeon, and at the end of the dungeon we poped out, and the quest NPC went from having a red icon, to a green icon, indicating that I can now turn in the quest. when I try to turn in the quest, nothing happens, so after carefully looking, I noticed I never got the quest item from the dungeon. I proceed to run the dungeon again, still does not work, so I go to reddit, and look up the quest, they suggest trying to run it unsynced. so I do, it still does not work, I run the dungeon again after that making sure its not on hard mode,

I can not drop the quest and pick it up again as it is a main story quest, running the dungeon does not give me the item, and talking to a calamity scavengers yield nothing as well, I am at the end of my rope and if I cant get past this bugged quest, I am going to unsub from the game, as no point playing if I cant make progress.

the Item I was supposed to have is the Wardstone from the Sunken Temple of Qarn on normal
