I just watched this happen on my team. One guy was attacking a teammate of mine in war and unable to get 7 flames. He got up to 5 attempts, according to the war screen. He then flew at least THREE more times but instead of quitting or completing the attack he ‘timed out’. This did not increase the attempt counter because it stayed at 5 the entire time.
This is a blatant exploit and would appreciate it getting fixed ASAP.
