The Rumble Clock appeared to speed up significantly after the morning maintenance on the server. It has said that there is 1m left for the rumble for 30 minutes now.
Even more interesting. My clock now shows 54 minutes, another guild mate's clock shows 6 mins. We should rename the rumble... The Twilight Zone Rumble
Oh, we forgot to mention the random time travelling feature in the release notes! In all seriousness, from the sounds of it it's probably a UI issue - each guild member will have the Rumble actually end at exactly the same time, but the UI will just lie about when that is, which is obviously not optimal*. If your guild has been affected by this, we'd really appreciate it if you and a couple of people in your guild could PM me the following details: Guild Name Player Name Player ID (found in Log > Settings > Help) Device and OS version *Understatement
Restart the game, the timers will eventually sync. The error occurred after the last server maintenance, possibly DST issues, but we found a refreshing of the game eventually fixed the problem.
