This seems to be happening frequently for me, I thought it might be one of the Hyuugas in the forest, but after today it can't have been that. Okay, so here is the deal. I had been fighting in the forest and was left with 2 Chakra points. I had run into Hiashi, not sure if he steals Chakra or not, but anyway after I had beat him I had gotten enough to get to level 7. So I fought my master and got to 7, ready to fight a specific person (Not sure if it's spoilers for those who haven't fought him) and when I started the fight I had no Chakra. Okay, even if Hiashi does take some, I should still have had 1 Chakra point from the level up, right?
