OMG so many people are like yes i want building to stop when buff runs out
BAD idea, Not everyone has everything buffed all the time and run things unbuffed so what would that mean??? them wont work unless you buff it seems silly to me as if you have correct eco balance you dont need buffs unless want extras out of production buildings.
also why are so many wanting basically it seems like the game played for them? i want this stopped when buff runs out its to costly etc, simple sleep the thing if buff/mine will die before you go to bed or add a refill in it to make it last longer there are ways around it rather than having it stop as buff no longer on it,
as for the FT castle comment seriously if you buff that with a hotdog/rainbow whatever at least do it at a time you know you will be in game when it is due to run out OR before you start your castle off send the excess beans over what buff would use to a friend in trade get them to decline trade so it stays in your mail until the buff over, castle sleeping and safe to have them in storage and not worry about them getting wasted, (thats if decline trades still stay in your mail personally i wouldn't know as never use that method myself)
the game is not meant to be all automatic done for you and mostly needs patience than anything to play the game.
It is your island to be how you want it, some want buffs all time some done etc a few want things sleep when buff runs out again that would affect them who like running with things unbuffed so personally i dont feel this is a good idea at all from any the previous threads all merged to one
