So a few days back, I added Sword of Berserk: Guts' Rage for Dreamcast to the database because I couldn't find it (and I searched under multiple terms like "Sword of Berserk", "Guts' Rage", and "Sword of Berserk: Guts' Rage").
However it was already in the database and I ended up making a duplicate listing. After it was pointed out that it was a duplicate a day or so later, I searched for it again, and this time the original listing showed up in the first search.
I just thought it was a random glitch. But then I saw in the Duplicate Listings thread that this user had the same problem:
Black/M...the last, I'm sorry for this one cos I'm the one that created the duplicate even though I used the search function. At least I put all the informations in the listing so maybe you can merge both. It's for the special edition of Dead or Alive :

So I think something is going wrong on the website.
