Well, didn't have to log this time. The server went down and took care of that for me. That was Drinal and it was brief thankfully. Nope, it was not just a rolling restart of the zone I was in. The server was locked for a bit whilst a problem was investigated.
Here is another example of of a new agent, duplicate iconic, failing to appear for duty. After camping to character select screen and logging back in, the agent has gone missing. Instead of 2 Lanika, I have zero. Also the zero counted drake and the orc are missing. After I log out to desktop and log in again, more then 10 minutes have gone by if that matters, the agents are back in inventory.
On Beta, there's a possible fix that went active from today's patch according to Niente on Beta forums. So might check that out ...
