Bug when start of battle

[R215907103]

Why Ever since the New Lucky Tree Event started, i have been experiencing system hang whenever i enter into battle. My screen will hang when i start to go into battle both in simple battle mode or not. All events like gauntlet, compare with other players, TD, Dark Abyss and Totems. I have to reload the page to proceed and then when i go into battle, it hang again. and it happened since the eventlucky tree coming. Please look into it
