I've heard that the ruling for bug exploits are as following :
if you win an x amount of rounds AND you use the exploit (even if the exploit has no impact to the round) the x amount of win will be rewarded to the opposing side.
if you lose an x amount of rounds AND you use the exploit then nothing changes
VK uses the bug for 6 rounds and win 4
The score was originally 13-8 but VK loses 4 rounds and ACE gets 4
(13-4) - (8+4) = 8 - 12
now the question is how does it became 13 - 8 for ascend? they got it from accumulation economic, and the results unfortunately favors ACE
