I bought admin yesterday and i had also bought for 400 game cash the premium on pvp fest still it says i am premium when in game, yet i am admin on all the other games another problem for me in pvp fest is my fire/lava resistance dosn't work
Admin ranks are not suppose to be able to buy /premium anymore. So it probably overwrote your admin rank on pvpfest.
It that case since you are only suppose to have one or the other it probably recognized you as having a rank on Pvpfest already so only implemented it onto the other servers. (Simply put)
