It has been nerfed a couple of seasons ago, sometimes it might go back to 500 because of a bug but then the GM always corrects it to 450. I don't know the reason, but I think it has to do with reducing the impact of having all the enchanted buffs in the alt+b menu and custom jewels.
No se si lo haz resuelto, pero tienes que hacer un ticket en la parte del foro donde dice "Contact Staff" ahi te lo resuelven en el día. No hay forma de hacerlo por ti mismo sin ayuda del GM.
It is understandable but the other option is to do it by hwid and that would make that many people can log many boxes in pvp zone, so I am sorry to tell you that you will probably have to deal with that.
The alternative that solves the problem places 95% of the server at a disadvantage.
lo único que puedo decirte es que si no sabes es por que no haz jugado olys en muchos servers con gente experimentada.... no es bug, ni siquiera es una habilidad de la clase...
