It seems today’s Pokken Tournament update, which was intended to fix some exploits and bugs, created a major inconvenience. Players in North America were treated to a slightly different “1.2 patch” than the rest of the word, effectively isolating the region from the rest of the world. Many things will no longer work, such as friendly and ranked games, because North American users will not get matched.
The reason for this is the Shadow Mewtwo exploit. Players have discovered that Shadow Mewtwo’s light pillar in field phase operates differently in North American 1.2 versions of the game compared to the rest of the world. With two versions of Shadow Mewtwo now in the game, North American servers cannot handle the conflicting data.
North American servers have now gone under maintenance as of this article’s writing, so a fix for the error may be in the works.
