Neither of those things happened here.

The examples people found include a monitor showing random technical text that someone asked a LLM to write (presumably the writer who goofed is getting paid) and some localized subtitles that were left with a machine localization (the rest of the localization was contracted out).

Even assuming a bunch of other stuff in the game was AI generated and just went undetected, which is likely, if it’s all iterations on what people noticed it definitely doesn’t fit your description.
