@EA_Blueberry I am sorry that my poor english make me confuse what you said. I guess you are asking what I had done before the error appear?
I didn't do anything, only that I gave up playing the game for two or three years already. I returned at about one month and half ago. while at the beginning, I didn't know I can't leave my league until I playing event that told me to join the league. When I try to leave the league, system told me should pass leader to others, but I can't do it either. After that, I started to kick out others who don't play the game anymore either. Finally, there is no one but me in the league. And then, the error showed up.
