Pirate Treasure and Treasure Mine just popped into two of our towns...
I have both of them as well.
I have them too. I looks that at least three members have events too. Treasure Mine I have second time in last last 10 days. I think that main developer of town has lost vision and strategy what to do with this game and they are throwing events just to cover they confusion.
Those events started for me yesterday. I’m pretty sure we’ve seen lists like this before, with the same events repeating at short intervals. It’s just different groups of players will get them on different dates.
I wish they would explain why they started doing this. Everyone not having a given event at the same time messes up other things (like daily event star tasks). I think it may also have led them to drop event tasks altogether from regattas. It’s been a while since I’ve seen one, anyway.
