On 08/01 we cleaned out all RPG data for players under level 60 that had not played since 03/12, any characters that were previously banned, and all characters under level 10.
This was done based on your CD-Key hash, therefore if you played any character within this window, your data will be saved.
This shrunk the size of the RPG data file from 13.3 megs to 1.3 megs and should have a substantial in game performance boost for the 5 minute window when this file is saved to disk.
If you've lost RPG data due to this clean-out, you can see this post for information on how to recover your data here:
The fundamental problem is this: The first word we learn as children is NO. From that point forward society teaches women that saying no isn't polite, and society teaches men to respect those who wont take no for an answer.
