Hi @cole_2018 thanks for the information provided.
Could you please provide a video that demonstrates this issue.
In the video could you show the 4 duplicated items in your inventory and show that you cannot upgrade them. Can you also check to see if you are able to dual wield two of the duplicated items.
I would recommend uploading your video to a video sharing platform such as YouTube, you can then copy the URL link into this thread.
@cole_2018 Thanks for the question! To share a video here you can take the video and then upload the clip to YouTube as an unlisted video or Google Drive and then share the link here!
@Cole_2018 Thanks for sharing this video with us! Could you also tell us what you did last before you noticed the duplicates in your inventory? For example, did you see 3 Hel's Scythes immediately showing in your inventory, or did they individually show up after completing an objective or another action in-game?
