The Last Stand Union City works, as far as I can swiftly see, with offline (local) saves, so on your machine, not stored online on some server.
These get stored in so-called flash cookies, more technically known as LSO's (local shared objects).
If you have your machine set up to automatically clean cookies, e.g. on shutdown of your browser, or of your machine, or if you regularly or occasionally do so by hand, these savegames will get deleted.
You will need to look into the appropriate settings in your browser or elsewhere (e.g., any cleanup software you use; check also your Flash Player settings) to make sure you keep at least those flash cookies you want to keep.
ps So what's a cookie? https://en.wikipedia.org/wiki/HTTP_cookie .
Flash cookies are technically not the same, however your browser or machine will typically clean them up, if you set it to do so, along with any cookies proper. So you need to look into setting it so as to prevent this.
