Are VIP's not getting their monthly coins anymore? cause I haven't gotten mine in at least two months. I submitted a ticket with no answer but to ask in the forums? Gee thanks.
1) It's called "subscriber", not "VIP".
2) You get the crowns at the beginning of your subscription period. If you sub month to month, it's 1500 every time, but if you chose the 3 or 6 month version, you get all 4500 or 9000 at the beginning and then nothing until your sub renews. Could this be the cause of your problem?
It's also possible that there's another bug, Xbox had problems with it before.
