I was just playing and my owner wanted me to do something for her so I dropped out for a few minutes.
When I came back and logged in ... it said I was trying to use an outdated client ( or something along that line ) and then kicked me out the the launcher whereupon it downloaded a smallish patch ( apparently ) and then I was able to log in again.
I had downloaded the Monday morning patch yesterday so it wasn't the weekly update.
Have they actually figured out how to do hot patching without shutting everything down for hours like they do on Mondays?
If I wanted a Signature I would have a Signature --- but i don't want one so I don't have one.
