Please assist.
I am unable to progress further in the main story line as I am unable to actually complete the quest "Give It To Me Raw"

I took the task as requested by the npc Drunken Stag, but upon completing I went to the npc and received the following message:
Drunken Stag: How did you fare, friend? Did you find the raw Nashachite?
At this point no further message was received but the 'Green Tick' was still there, and my journal still shows this as current with the 'Green Tick' showing.
I would also like to note that the 'raw Nashachite is no longer showing in my 'Key Items' of my inventory.
I was also in a party of two players and the other player managed to complete this quest successfully and is able to carry on with the storyline.
As such, I am not able to progress in the story line and I kindly request that this is looked into asap as I had hoped to achieve level 45 before the end of the 'Lightning Strikes' event, and this bug will definately slow down the process of gaining experience points effectively.
