So while playing through the game I came upon the quest Oh my Papa, and so I had to talk to a few people about breaking the alliance with Caeser so I went and as soon as I got to Jack, I had a speech challenge which needed 60, so I had 70 speech and I did and I passed the speech but then it gave me the same message, over and over and over, so I mashed A and B at the same time as fast as I could and I was getting 264 XP per time along with the 198 XP for doing it 3 times, so I did this until I was level 30, and so I thought I would share this glitch with the rest of you
