A mini patch 1.0.2 came out for Starcraft 2 recently, nothing too earth-shattering in the change log just a couple Single Player bug fixes

Bug Fixes

* Fixed an issue where campaign mission victories would not always trigger properly.

* Fixed an issue where some players were unable to access single player features.

As you can see nothing too spectacular, but I suspect there are probably a few unlisted changes behind the scenes since a few more bugs have been plaguing users, including the infamous GPU overheating problem.
