Purple And Blue Quest Bug

So I finished the quest Purple and Blue and brought back the magical fragment and helmet back to Korun. When I talked to him, my inventory was full, so I dropped a few junk items and gave him my helmet and fragment, but during the conversation I accidentally picked up the items again, and at the end, the quest didn't give me the rewards because my inventory was full. However, Korun still kept my items, and are asking for them again.



I have another magical fragment (phew), but the helmet is impossible to get since it was a reward from the previous part of the quest.

 

Does /fixquests work??

 

Aha! Didn't know that was a thing. Thanks a bunch!
