Plutonium

While playing T6 Zombies, all of the DLC maps I got from the torrent seem to be somewhat broken. (I'm using a steam install of the base game btw). Some text just seems like something that would be used internally to specify what text is supposed to show up, but it doesn't.
As you can see, the names of quest equipment categories, tutorial text, and map specific functions are having this problem. There are some smaller things that are also affected by this.
