This time, after playing through the teas event, I closed the game and restarted it, only to find that my progress on the teas event had been reset and I had to start over from the beginning. I think it was after I had played for maybe half a day. At first I thought it wasn't a bug, just a data sync problem in my environment.
But I noticed something: the first badge on Tea is now two badges. That means it was syncing. So I think this is kind of bug.
Personally, I may be lucky to get the first badges x2 for TEA event, but I don't like not having the same number of badges for TEA events. I don't like not having the same number of badges for TEA events because it is a sign that I didn't complete the event to the end.
I would be happy if support team could either increase the second and third badges by one count or decrease the count of the first badge by one.
