As an addition Ill add that the In Game guildlist is cleaned. Lots and lots of names have been booted, people that have been offline for years or simply quit the game maybe just a few months ago.
In this process some Alts have been accidently kicked no doubt. This is because its impossible to keep track of all the names. Who is main who is alt whos alt is whos? Some alts will need to be retagged.
