Knight of Gods are different from World Government, they're all out of touch with outside world and only go out of Mariejois for missions. They're even worse than Celestial Dragons in terms of looking down of others. In their perspective, there's no need to know bugs and what happened to them. Especially when they're immortals and have lived for so long, it's understandable to just not care anymore.
A Knight of God doesn't know/can't recognize Ivankov?? One of the founding members of Revolutionary Army, and one of the most wanted person in their world?? ridiculous
