We've been considering how to best approach the issue players are having with needing the final blow in order to gain credit for the victory. We looked at the feasibility of a hotfix at this point in December. Unfortunately, with the holidays and the timing it will not work out. We do not want players to miss out on the reward. We want you all to be able to relax and enjoy the seasonal with out stressing over the combination of RNG and needing a final blow, as that was never intentional. We feel that the best thing to do is make sure players get the seasonal reward at the end of the event whether the Matriarch Objective is completed or not. Players will be receiving the reward at the end of the event regardless of the status of the Matriarch specific Objective. Apologies for the inconvenience. No get back to shooting and hacking up zeds in true holiday spirit!
