It's working, but there was like a 24 hour lag or something like that.
Frankly, Prestige Pack isn't worth it, considering that if you spent $15 of ncoin on event items, you'd be much richer off than the 1 EAR or Rgem that you get a day. I know you get other benefits, but altogether still not that great. They need to update Prestige Pack with better items.
