A lil somethin somethin: You can find the details for this event on the announcement page here.
An issue was found in which items were duplicated. This loophole in the system is our fault, and we'll be fixing it as soon as possible. We apologize for any inconvenience this may cause.
However, intentionally using duplicate acquisitions is a clear case of cheating and will result in a suspension in both Normal and Ranked Matches, and Ranked Matches will result in the forfeiture of Rank Points. This behavior is clearly evidenced by replays or other means, so we ask that players who play normally not abuse this feature.
Also, if you see any cases of abuse, please report them to our Support Team.
We apologize again for any loopholes in the system and will do our best to ensure that normal play is not disrupted.
