There was a bit of database corruption that caused some characters to disappear, and it has been corrected with a rollback. If you've done any recent leveling/looting, you may need to post
here and list what you require replaced.
For the future, this site mainly handles issues with the emulator itself (things like AAs not working), and
ProjectEQ's forums are where you'll want to be looking for information on that specific server.
Hope this helps =)
