You have to realize that most times when some one subs out they are hardly heard from again during that game, which is why we don't have the clearest rules about this sort of transfer.24 hours is plenty time. If it's 48 hours I can sub-out before the votes are counted while placing my vote. Get a sub shortly the next day and then my sub can get a sub of itss own and have it announced within my original 48 hours deadline. Then all 3 of us can sit around and collect information which we can freely pass onto each other. 3 people - 1 character. That sounds so horribly stupid.
This is a very special case where a player lost interest in the game and was subbed out (something that I consider poor sportsmanship to begin with) and then once something happened to his sub reigned interest.
