How do you gain value points? I noticed now that i maxed out most of everything my value points slowed down dramatically, now i get a few hundred here and their after a lot of games. do you have to keep ranking up in other stuff to increase value?

Also i have started going for that ribbon that you need to place 3 bombs and detonate all 3. the problem is i have done it twice and i have done it one time and it didnt register, is that a glitch.
