The game tracks how many are opened for achievements.
Can you display it for us to see in Stats, outside of the achievement progress bars? It also hasn't shown in Fanta site, so it isn't public at all for us. It isn't meant to be hidden, is it?
We can look into adding those values to the Stats screen as well.
Thanks for hard work. Maybe we can have the mega and ultinate event chest to buy with event currency ?
Event chests are little rarer, so they won't have large versions.
