A few words of explanation, because players simply deserve them.
The point was that if a player finished the first wave with a number of points associated with a reward (1, 4, 8, 12, ... , 200 points), there was a bug. In each battle in wave II, players received an additional reward from wave I for each battle.
For example, 64 points meant that the player received a gold chest for each battle.
72 points gave a ruby per battle.
This even allowed players to earn rubies because (16 expeditions cost 5 ruby= we gain +11, then 16 expeditions = 10 rubies, which gave +6, and another 16 expeditions = 15 rubies, i.e. +1). A total of +18 rubies/30 minutes and another 48 points/30 minutes, which allowed you to get closer to the leader and sometimes even overtake them.
The update came out. Quietly. No apologies to the players. No compensation whatsoever. Those who spent their rubies and were overtaken are surely happy. Only GF is capable of spitting in our faces like this, unfortunately. Rudeness without limits.
