This is OP's fault.
But still this does not change the fact that it is bad design on the quest.
There is no reason to not give players the "2 item turn in box" or something, noone is gonna soulglaze only sword or shield on purpose - this shouldn't even be an option IMHO.
You can not excuse the bad design of this step of the quest by saying step one is the same bad design. It does not get better by repeating.
This game rocks but noone needs to defend bad design..
