Before upgrade to the new path, i already receive mail christmas boots but not vanity skin so i install the new path but is still not receive any mail about vanity skin.
its possible that youve already recieved a holiday vanity skin set, in which case, theyre always the same. therefor, you wouldnt recieve duplicates.
I do not have christmas holiday vanity skin set, only the halloween one.
Shoot me an email at email@example.com and I will try to help.
