Erm well i saved up 3 prestige tokens i know its double xp at the moment so using a prestige token on double xp would mean quad xp first prestige token worked fine but when i used the 2nd one it look it from my credits but didnt give me anything is this a bug because i didnt select anything else but double xp

If this has happened to anyone else or you know why its done this please let me know.. not going to use my other prestige tokens whilst its double xp weekend :S
