Something very strange just happened. I was doing raids and things were going nicely, so after using up my flags, I used a flask and I proceeded on. I saw my cups climb up gradually to 2761, then won 30+ cups from another raid. I then quit and that’s were this turned absurd. I got the message that one person took revenge. I was online, but I know how how this works. The weird and bad thing was, that I had dropped back to 2617 cups. How is THAT possible?
After writing this I went to check on the game one more time. Somebody attacked me, -40 cups and now it says 2754 cups. So no harm done in the end, but it was definitely very confusing.
