Im not sure that some one didn't write about this but I dont have the time to read all the threads. So the bug I noticed happens when you login and you have send an explorer for treasure. So when I logged In I clicked ok on the reward for being on-line for 3 days in a roll. Then I got to the messages and accepted those rewards from my treasure hunts. But in the same time I clicked to accept the reward from the explorer the reward for the 3 days in a roll log came. But it was not in the mailbox, so I closed the mailbox and when I reopened it I it contained the reward for the 3 in a roll log in and the rewards from the explorers again. It was good to get 2 treasures but its a bug so im reporting it hope I was of help. Best to all
