So long story short, the 0.10 update has changed a lot of things involved with running the servers etc. and is a bit more complex than first thought. With that in mind, we've had to postpone this event until a fix can be found, so right now this event's currently set for TBD.
Thanks for your patience, and apologies for the problems, but a lot of it was out of our hands as it arose just minutes before the booking time was about to begin.
Hopefully it won't be too long of a wait before we can throttle these things round the ring
