If you’ve been playing Killzone: Shadow Fall, you probably downloaded the recent patch, Patch 1.14, which contains bug fixes as well as preparing the game for its upcoming DLC. There is, however, a new glitch that has come with the update.
When you bring up your career page, don’t be alarmed if it tells you all of your challenge progress appears to have been erased. It hasn’t. The glitch affects the way the information is displayed on the playercard menu, but your actual progress remains intact.
The above image shows an example of the glitch. Again, this only affects the playercard, not your actual challenge progress. Guerilla Games is working on fixing it.
