It's ridiculous if we think that they don't know where the problem comes from. In the last update, nothing was added to the game that caused this problem. The events were there before the update. If the server resources are not enough, the events could be deleted. If It is added in the programming, everything can be returned to the state before the update, but when the problem still persists after two weeks, it means that there is no decision to fix it.
However, you can post for days and times. It does not affect the process of solving the problem. What I imagine is that a programmer, late at night After work, he looks at the codes for an hour and decides to look more closely the next day if he has a chance.
Be patient. To fix a software problem,one month not a long time. Of course, in Big Bug game.
