Of course grandpa, but maybe the solution could be to set the free will to low or none? After I set mine to low, my guy haven't done this again.
I'll have to give your suggestion a...'think-about-it'.
Well, I've thought about it and chose to cash in some LTR changing out the 'Loves The Outdoors', rather than lower the 'free will' thingy. I very much enjoy seeing my sims choose what is choice to them at the time. I also appreciate the effort of balance the good folks at EA put into the game.
To my way of thinking the sprinkler obsession, just because of 'Loves The Outdoors', is either an unbalanced quirk or a deliberate "hey lets have some fun with ts3 players" by game developers. After all it is cataloged in an odd place.
My gardening sims seem unaffected by the loss of 'Loves The Outdoors'. They'll go about the gardening chores, all day if necessary. They don't have to spend from dawn to dusk doing nothing but watering plants with a water can, since auto sprinklers are now in place.
Not one instance of 'playing in the sprinkler' has occurred since the change. My sims remain happy and balanced.
Again, thanks to all who weighed in on this one. Your thoughts and provocations were appreciated.
