Title Update 14 (TU14) was an important release which was launched after months of speculation. The update received much attention because it brought up a slew of new features to look forward to including jungle temples, desert temples, riding a pig, invisibility, trading with NPC villagers among many others. With so many new game play elements being introduced with a single update, it was obvious that the players wanted to try it out. The game producer proudly announced on Twitter that over half a million new players thronged to play the game when TU14 was announced but with so many features into it, it was obvious that bugs were prevalent as well. They were related to multiple features found in the game and it stopped them from working as they are designed to be.
The game developers 4J Studios were quick to react as they developed the Title Update 15 which addressed over 15 different bugs and submitted it to Microsoft for certificate testing. The company has finished the testing within two weeks and has rolled out the update which has already been downloaded by a record number of players. It fixes a lot of issues including voice problems during split screen game modes, animals climbing cobblestone walls, invisibility potions not working on sheep and gamer tags among many others. After having successfully released the update, it is expected that the company will now start working on the next gen version.
