I've got a problem with the chapter 4 Konoha Invasion. It says I need to earn 51/51 Battle Points. I've done all the missions with 3 points per each, but anyway it says that I've done only 42/51. Can't get where is my mistake.
You have three more plot instances for Chapter 4 to go (Serpent's Rampart, Reconnaissance of Orochimaru's base, and The Maiden's Genjustu). So, no, it's not a bug :D
