Sorry about the downtime during the last few hours of the event everyone.
Due to the unscheduled maintenance, we've decided to extend the Beckoning Nightmares event by 1 hour, and also have a code available for free ironite as compensation for the untimely maintenance. You can get the details from that from Leviathan's post in the event thread.
Thanks, I'll pass that along to review the logs.
It was not a scheduled maintenance; basically, a problem occurred with the server that brought it to a halt, so we felt that communicating it was a maintenance while the team was working on fixing the issue was the best way to communicate it with what we had available.
In the case of a MACL15, there is a known issue where that will sometimes occur at the end of a PVE match. However, in most instances that I've heard our CS team has looked into for that, the rewards are given, they're just not communicated when you next log into the game.
If you're confident that you didn't even earn runes from the battle, though, you can send a message in to CS to check, but you'll need to be very specific about the date and time it occurred for them to verify (our logs will just show your battle results giving normal rewards in that scenario).
