As I was playing, I noticed my Level lowered by 23 instead of 24. It shows up that I am level 23, not level 24. But as I return to the chat room, It was Level 24. At the next battle, I'm still level 23 not 24, but after I defeated the player, It gave me twice the reward (4,300 or less). Odd to see it reached from 4,600+ to 11,200+.
