This is only ment to be a example but this has happened quite a few times.
As you can see. (T.A) Hideyoshi has a blank line of text appearing at the same time is a what looks to be a sleeve drop. Though obviously it's fake since (13) isn't actually a potential sleeve drop. A little later the real sleeve drop happens. You can easily put any number in there if you know the spot the prize sleeves are in.

Can you make it so that the lottery can't be faked? I dunno maybe Bold Text or Special Color or Text that can't be used by the players?
Also Dupe Sleeves drops have been addressed before but I would like it to be reinforced.
I really feel like I should not be wining a sleeve I've already had. It wastes the 45 mins of waiting there for a sleeve only for everyone to get nothing.
Can you please make it so that a player doesn't win a sleeve if they already have it and if they already have all the sleeve possible from the lottery (future potential case) have it generate a new winner?
