I'm curious, how was this missed? Surely you guys at Lightmare have regression tests and a QA system that mirrors live to test on?
Your assumption is that an alteration made to the server or database would have caused this, and that's incorrect.
There was no patch, there was no alteration made whatsoever. This was a freak glitch. At approximately 3pm IWT August 9th, users reported fervently that logging into the game was impossible as the client was getting stuck on "Account Authenticated" and would not progress beyond that point.
What we discovered, was that something happened to where multiple portions of the database became locked off to the purview of the client after a minor overload. Over time, more and more issues have been uncovered related to this overload, this was one of them.
We have been, and will continue to take steps to prevent things like this from happening in the future.
