P.S.
If you know how the engine rly works, it's rly not hard to understand what caused the issue, but most people here are not "client developers", they are content makers, they have no idea how engine works and they never would be, to say honest it takes a lot of time and energy to study all that things, and just to help on comments on forums =D huh, its easier to ask original koreans for same help.
