Do you miss something on BrainKing.com and would you like to see it here? Post your request into this board! If there is a more specific board for the request, (i.e. game rule changes etc) then it should be posted and discussed on that specific board.
So if the game has a 3 day limit and you went on vacation after 2 days, when you come back there is still only one day left. This is how autovac should work.
Also autovac shouldn't be allowed if the player has logged in that day in my opinion, that invalidates the reason (emergency etc). If you're playing too many games timeouts are a fact of life.
