They take longer than they used to, I also sometimes notice a delay when I pause my game (it takes a few seconds before it pauses) or when I try to go to speed 2 or 3 and back to 1, it doesn't go faster or doesn't stop immediately.
Thank you for the tip, I'll try that.
I'm afraid it has something to do with the fact that I've played this save for quite some time (IDC on gen. 4). So maybe it's a similar problem as with the sims 3? When I played the legacy challenge I started having problems around gen. 6 / 7 because I played the save for so long and more and more problems occured. I hope it's not for the same reasons since I like to play one save for a long time.
However I must say it just started recently, after the patch from June 2 maybe? Not sure about that.
