While not the biggest of patches, the 1.2 Update is pretty substantial given that it arrives almost three months after the game’s release.
Despite the changes, players are still wondering when the GWS (Global Wonder Station) will be added in for worldwide trading. Some have speculated that the feature was delayed due to cloned Pokemon, which ILCA seems to have just fixed permanently.
