When a Server starts up there appear to be a small time-window where a char gets wiped when logging in too soon.

Symptoms: Some Servers will change their server time fast in the first few seconds. What you see is a quick change of the server time when you hit refresh on your server list (best done in favorites)usually I see:

8:00, than 9:20, than 12:00. After that the server runs stable and it is safe to login. If you login before the server reaches 12:00, you have a good chance that your char gets wiped. I had several char wipes like that before I figured out the cause. This change from 8:00 to 12:00 usually happens within a few seconds.
