I had 100 friends when i got awarded gold account, i argued with a friend and we deleted each other, but as my account got normal again, i cannot add him back it allows me only 50 friends, i have 98 friends in my list now, should the account at least allow me 100 friends still? my gold account is another account of me, btw. At least, gold awarded accounts or gold accounts who had before might have been still allowed to add 100 friends even if their accounts turnt into normal.

Sorry, but we also have to cover our costs somehow. Please read:
