I think it is better to set this via single purchase or conversion rather than accumulated. This will create a lot of tickets for our CS Team and also I strongly suggested that players will not file any tickets for this. What we can do is to have a data pull then upon having the list which is verified we can start the awarding. Also just in case our CS team has a lot of task we should have the power to reschedule the awarding of the items which is announced properly.
