The server went down and the rewards from the breach boss disappeared.

I defeated the Breach Boss. After that, I got home, but the server went down at that time. When I logged back in, all the rewards were gone. It was fine until then. Why did the Breach Stones disappear even though I rolled back? I don't understand. Why did you take down the server without any notice?I don't understand why it's so easy to take away not only time but even the right to challenge, even though the game system requires you to consume things to challenge. Are they taking the players for granted? I want a quick response. Many players are being victimized. If this response is left unchecked, it will affect future gameplay. I want to continue enjoying playing this game. That's why I want it back.
