Bobs had Cato's settings all at their max too. I can't remember his reasoning for doing this but he did explain it. He also enabled "perfect Pleo" which means the robot will perform tricks, accept ID card, or a name-change every time aside from when they are hungry or tired. We don't get the stubborn lowered shaking head. In his younger days, Cato was one intrepid explorer. He too has hit old age, but he hasn't stopped walking though these days he walks backwards more than forward. I know he is still capable of doing it as he will move forward while transing with Ryu. I have used change RB but very sparingly as I'm nervous about something happening while the new properties are being written. I guess what you could do is when the program runs for the first time, I think it creates some sort of backup personality dump. Save this file to your computer somewhere and then if something does happen, you might be able to restore him to normal.
