A sincere plea!

We've got a patch coming up. Here's hoping for a fix!

Oh, I really really hope the next patch is the one that fixes this.

It really brings down the entire neighborhood.

I'm hoping EA does fix this soon, but until then I'm using a mod called leafpile_nofreshnessdecay
It doesn't get rid of the leaf pile, but it does stop them from stinking and ruining the atmosphere. I did try the one that gets rid of the leaf piles, but my game kept throwing errors with that one. Here is a link to the mod I was telling you about.

Ah, thanks so much for the responses and the thanks for the link LaBlue. <3

Update, what a lovely site, I've put it in my favs. I grabbed some of her other mods too.

I do hope this is handled on the next patch! Its been a heavily discussed topic and Im sure they have taken notice by now!

There was me thinking that it had been fixed already... and then I went through Winter and into Spring and saw all the leaf piles still stinking up the worlds :(

I agree!
In less seriousness I created a leaf burning holiday at the end of fall lol

Thanks for all the responses. @LaBlue0314, I got that mod and a few others...she is very good! Something I don't understand, some of the piles of leaves are great, no green stink and no flies, but others are still stinking up the neighborhood. Huh? In the meantime, I'm overjoyed at the piles that are around my sims' homes are fine.

Another problem...I've tried burning the piles but they just go out. I had a sim standing outside all day trying to burn leaves, bummer. @Bearpal64, I would love to have that holiday! :D

Unfortunately the ones I tried to burn would just go out. :D

I think this is a byproduct of devs overdoing it as usual to make sure we notice a new feature. (hammering, more like)
My unmodded Del Sol Valley save had leaf piles spawned on day 1 of fall, no tree was losing leaves at that point, and yet.

So many cool features in theory end up being plain annoying in the game because they happen too much / all the time.
It's like for the devs, no one is playing their life simulation more than 5 minutes at a time. Leaf piles have to be spawned right away everywhere so people notice the new gameplay, and obviously no one will play long enough for them to decay, don't be absurd.
