There is currently a bug that if you beat any Mob on 6-1 to 6-10 then sacrifice and the reward is a green exp totem, this totem will only be a Exp 2 totem. If you Sacrifice before you beat a mob on level 6 the reward is a Exp 3 Totem as it should be after clearing level 5.
I have not yet beaten 7-1 to know if this then correct itself for Level 7 Mobs.
