Hi everyone, I have looked into what is causing Cursed Quests to ask for this invalid item. I will be pushing a fix within the hour. I'll also be deleting all of the glitched items, so if you got one somehow, please leave the item in your inventory for now.

[edit] I deleted all the copies that were mistakenly given out, and I've pushed a fix so the issue should be resolved. It may take a few hours for this particular fix to finish going live however so please don't worry if it still happens for a bit today.
