Core Data Suddenly Losing Changes

I've been working on a project that uses Core Data for a while now. I recently changed the model and ran it, but I noticed an odd behavior: I wan't informed that the model had changed and was incompatible. I went ahead and deleted the old xml file and when running the application again, it created another file. The only problem is that Core Data has stopped saving. EVery time I open the application, I'm presented with a blank slate. I haven't been religiously using subversion, but I had a commit several days, so I checked out that revision. It has the exact same problem, but I'm certain this wasn't happening a few days. I'm not sure what I could've done that could have caused this, but I'm completely stuck and going crazy trying to get my app to work again.

Thanks,
- Walker Argendeli
