Fix broken achievements in garden warfare 2

There are 3 types of achievements that are unobtainable, boss hunt achievements, cats vs dinos achievements, and community challenge achievements. Me and most people in the community don't have them and can no longer obtain the achievements because the features to get them are no longer in the game. If you could add them back I will buy all of your dlcs for the game. Making your effort worth it.

Thank you for your time, Oliver Pinch
