Where's my UFO?

I don't have the UFO flying around my city like many others do. I did a time cheat about a week or so ago and all my constructo coins disappeared at that time, but everything else is okay. I only went one month ahead on the cheat. Am I still going to get the alien?

BTW - please don't suggest resetting my game. I'm not interested in doing that - I have 30 sims and I'm on level 38 so starting over is not an option.

I suggest not using cheats again. It has been known to cause all sorts of issues in the game. Data corruption and such. If this happens you will have to start over and I doubt you want that. So. Did you save to the cloud before you used the cheat? If so you can just download in and have your UFO back.
