I can sympathize with your frustrations, not just with the game, but the wondering if EA will get "this" (whatever one it is) fixed soon.
I can agree that a lot of the bugs are from EA, but I have had some problems with my computer causing the bugs. My computer can handle only so many games, expansion packs and then it starts having a fit and creating all kinds of bugs, from sims sinking into the ground, warped, strange looking beings, routing issues and others that had me wanting to pull my hair out.
Uninstalling an expansion pack, deleting some big saved files and my games play is fine now. I just have to watch how much I put on my computer.
I guess I am going that EA does at times seem to be dropping the ball in the area of bugs, but sometimes it can be due to a player's computer, sound/video cards, power levels and whatever else it can be it just can't handle the games.
My computer can handle only the base game, WA, IP, SN and I think it is four of the store worlds, more than that and I have so many problems it makes it too buggy and frustrating to play.
I hope you can find a solution, it can be frustrating to want to play and not be able to.
