mystery quest re-do

K ill try explain as best as possible. I was doin the quest to kill 500 aliens for mystery sword, and I was about 2/3rds done when I bought the mystery staff recipe. So I finished quest and forger my new sword. After, I had no quest to get materials for my staff, an extra sword codex (which I accidentally liquidated in hopes it would fix itself, and the staff recipe. Now I'm stuck with this recipe and I can't get materials! What do I do? Devs, is there anyway u could reset the quest for me?
