A new patch for Bloodborne has been released and it fixes a number of issues and exploits found in the game. One of the biggest changes includes a fix to a well known duplication glitch that was spreading through the internet.
The item duplication glitch allowed players to practically duplicate any item in their inventory, and many players started to use it to get infinite consumables and increase their in game wealth. Whilst this duplication method has been fixed it would not surprise me if other players manage to find another dupe method before From Software have the chance to fix it.
Another very important fix in the 1.02 patch changes the way a certain mission plays out, which previously caused some issues, stopping players from progressing through the game. If you ever had trouble with the Lunarium Key in Bloodborne you will be happy to hear that all issues relating to the key have now been fixed.
If your game was previously unable to make the key spawn, you will now be able to head into game and collect the key to continue with the game. Without the Lunarium Key, players cannot fight the boss within that area, and that will stop the player from being able to complete many other areas in the game following on from the boss fight.
Whether or not you're frustrated with the item duplication fix, I think it's great to see the developers of Bloodborne working quickly on major game issues and bugs. Bloodborne has been incredibly successful since it's release, and millions of players have already purchased the game.
