Well our rumble timer has been sitting at 1m for at least 20 mins. I have closed the app and re-opened it and it's still 1 minute. @Lynsey [Midoki] any word on this?
It's a UI issue where the time displayed isn't the actual time left, and can vary from guild member to guild member - we're looking at fixing this in the next update. The server knows the correct time though, so Rumbles do last 24 hours and should end at the same time for all participants.
Usually we have seen if you kill the game and restart it, the timer will correct itself, but it didn't seem to happen today. Thanks for the update @Lynsey [Midoki]
