SureAI

I am a level 20-somewhat hero and have come to the point in this quest where you have to place the three statues on the circles to open the treasure box. However when I try to remove these from my inventory by pressing it with Shift+click it says that quest items cannot be removed from the inventory. Now this is not something uncommon since Ive seen this problem at the start of the game. When you get to the quest you have to find something to improve the wall defense of the mining base, the shovels you find cannot be removed from inventory and I still carry them. I didnt mind this since they were 0 weight, but now that I need to remove these three statues for the Darius quest line, I cannot.

Your help would be greatly appreciated

Have you collected already all 3 statues?
