Hi Scenicus, welcome to the forums.
I'll move this over to the Sims Console board for you as it's the more appropriate forum.
I'm sorry to hear that you've experienced this problem, I don't play any of the console versions myself but I've seen this problem mentioned before. I haven't seen mention of any glitches with other console or DS Sims titles.
I'm sure the admin staff here will pass on your comments to the relevant people within EA, as part of the their forum feedback reports.
