Okay, so I've been playing Mu-Lung Dojo and beated all five bosses. But after I did, the 5 chests pop up and I can choose one of them. However, when I chose one, the game just keeps loading. After a while, it just says "Connection is not optimal, returning to main page." My internet connection is at its fastest, but I'm forced to restart and when I try to go back to the dojo, it says the party ended and i ended up not being able to take the loot. Is there any solutions?
