* This bug was reported some time ago in the old EA-AHQ forum and has since disappeared, so here's a repost.
It's easy to recreate: You need the weather controller and have to upgrade it, where you can change the weather forecasts. After you've changed it, travel and return, and you'll see that the forecasts haven't been saved.
I found out back then that it might be a problem with Snowy Escape (EP10) or another pack, because if you only use the base game and Seasons, it works.
I own all packs, btw.
Edit By crinrict: Adjusted Title fit old bug report.
