Tapping spaceships question

Was wondering if anyone could answer a question. I have visited most of my friends today and have yet to see 1 spaceship. I cant even clear that task.
Are they just really uncommon or do people have to be at a certain level, or what?
Thanks

Same problem, no UFOs for me since initial quest UFO in Other Springfield.

I don't now if this is related but:
- I didn't buy Ray Gun / Kodos, so Kodos is still flying over my town
- I didn't unlock all FP prizes (Mr Teeny still locked)
