Yeah, I noticed I was getting ep too (PS3). I really only have the Red Lucy quest to do, so I can see getting past 42 for me. I m bring the deathclaw eggs to her now. I was kind of glad.......
If I broke the level cap I would be scared what happens when it says your level is capped at 45 and you are level 50? Could mess stuff up. If you want to do it, It's fine with me, I just think it may glitch things up later on. I'm on 360 so this doesn't matter to me, just wanted to see what it was about.
