Hi sorry I forgot to update this but Nuxl fixed this bug, so now we can all hoard pearl strings hurray!
Ive been doing sfr central runs to try get phione and collect pearls for my house. So the pearl string is the rare item from secret room, I got one and it disappeared from my storage, I was confused but I thought I must have just lost it somehow. But last night I got another one and this time I left it in my bag becasue I didnt want to lose it, but when I logged in next day it was gone. I checked the items in my bag to see if it had just done that thing where you move an item and it says the wrong name but no dice.
I wanted to decorate my house with them but if they are bugged I really like to know so I can just sell them when I get them.
