I noticed several battles in our team wars where the player clearly won the battle but it did not record in our War Stats and the war coins were not awarded. In several examples, the opponent showed defeated and the winner had 3 monsters alive; however, the war coin circles were all blank gray. In other instances, the war coins won did not match the number of monsters still alive.
I did a manual tally of our last war and found 11 battles for 8 different players was not recorded correctly. This resulting in a shortage of 21 war coins for all players on the team.
The total number of victorious attacks was correct.
It's easy to spot the problem. In the war log, the incorrectly recorded battles show a win with zero war coins. I'll upload screenshot examples of some of them.
I already submitted this to support; however, I don't believe they actually looked into it or took me seriously. They simply closed the case with assurances that everything was fine. The math proves this is a real problem and I have a spreadsheet tallying each battle and can clearly show the bug if anyone is interested.
In this image Cristian Chicea won the war with 3 monsters alive, but was not awarded all three war coins. Manual tabluation of war confirms coins are actually missing and this isn't just a display issue.
In this image, Leo Cao won the war with one monster remaining. No war coins awarded, confirmed by manual tabulation.
In this image, Crista King won two battles with 3 and 2 monsters remaing. No war coins awarded, confirmed my manual tabulation.
I have several more examples of the problem...but they are the same as the above examples.
