A new update has been created for the DLC and this one fixes a few minor issues as well as unlocks an extra mission. Also, there may be a problem with the DLC not loading correctly. If you download the expansion, make sure the Loading screen is golden in color as oppose to white, there should be a new logo, and on the title menu, in the lower right corner, the version number should be present. If you can't see any of this, please contact me. Also, the basic version has not been updated with the expansion's fixes so it is imperative that you download the DLC as the basic version will be fixed later on. It's free so there is no real reason not to. This DLC is only available for a limited time. By the 10th, the DLC will be removed and this game's support will finally end.
