I am not sure is it reported already but few things does not work as they should:
1. World Boss icon or world boss does not spawn
2. Lvl 40 Kiri Majin (Female) gives you same buff as lvl 50 Kiri Majin (Fat male) - 150 LP and 150 EP recovery per 1 min buff
Lvl 40 Kiri Majin Female buff should be 75 LP and EP recovery.
