Well, I don't. But if you can repro a world break and get a stack trace it will give you some idea as to where to look.

My repro steps for the problem where:
!. Try to create a character. Tha would fail at the last step.
2. Go back to character selection and create another character.
3. At the name selection stage, hit the name generation button. If it returns a blank name, you have a repro.
4. Keep hitting the name generation button until you get disconnected from the server. At this point world.exe has hit an unrecoverable problem.

You can get the stack trace from world.exe by launching it in a debugger. I use ntsd in Windows.
"ntsd -g world.exe"

hope that helps.
