Hi I have the same problem with Focus Sash and knock off. Sadly I only noticed it after about 3 more hours of gameplay. Is there no other way to get the item back?
Fern - future thingy?
I did the quest, but it seems to end with the finding of the dark material in the arceus cult chambers through the sanctum key.
Does it go on from there?
Because I didn't find Fern in there.
