The event timer of the last Raid Boss event still showed 1 hour left when the event ended. This problem also appears at the start of several battles (they started 1 h earlier than anounced). Making a shedule for a guild is difficult enough even without this problem.
It would be great if this problem could be fixed (and it was not because of the end of daylight saving in the US... like I said it happened in the last battles too)
