UFO and Picture Landscape

[jmshel]

Just upgraded to version 3S and typing 'ufo' didn't work. I tried 'firework' and 'fiesta' and they both worked. I use a landscape created from a picture so just for grins I switched to village landscape and 'ufo' works! So then I thought maybe the ufo's are flying below my picture, so I typed 'ufo' several times over the last hour thinking that eventually the randomness of the flight would appear in my sky - not one appeared. Has anyone else seen this problem? Any ideas why I can't see ufo's?

I would think that the 'ufo' uses a different algorithm than the other

'easter eggs' so it can only be used in a stock landscape...

Not in a custom landscape...

yes that makes sense, else I'm extremely unlucky and the UFO's never randomly fly into my custom landscape sky.
