The Bugs forum thread is not just for reporting bugs to the administration. It is intended to solve technical problems encountered in the game. Before creating a topic, you should check to see if there is a topic with the bug that you want to report. In order to report bugs or glitches, you can create a new thread instead of writing in the existing threads. Topics with the title Bug, Glitch will not be considered. Try to put a brief description of your problem in the title of the topic. If the problem described above occurred on another account, be sure to specify the account where it occurred.
I made a second screenshot in another battle. I did not find this particular battle. But like I said it's common and I notice it in ALL my battles with ALL units.
