I just joined and attempted a relic hunt and when the battle started, the game sat there for ages waiting.
Then it said something like your account is logged in on another device, login again, which is 100% impossible in every way. I relog and it sits there trying to "Reconnect" to the fight, then gives up and says "disbanded". Attempt at Relic Hunt lost for all members from what I understand.
When I got back to the main menu, the popup for new day came up showing events etc.
Weird! Did you have some kind of server fail?
*edit: one of the other people in the RH also said the game told them they were logged in on another device and they were kicked. Clearly something significant failing there, not our faults.
How's your database security? Was someone actually logged into our accounts just then with a bot or something? I've only ever used this game/account on this one device, from the one static WAN IP btw if you wanted to check on that; no other device or IP should have ever had anything to do with this account.
