The reason I am going to quit this game soon, it is because the SD customer service never solve my SD account problem. My SD account's ability slots are lost due to some kind of bugs or problems! Furthermore, the game will CRASH EVERY TIME "ability acquired"! Already reported this problem to the customer service since 01/25/2022, but the problem still here. So please solve this problem ASAP, because I can't change my ability accordingly to opponents. THANKS.
