This is (I'm pretty sure) because the "Save Release and Quit" option 
kills the existing world, that is re created on startup. By the time the 
script is run, the world doesn't exist. But after re-saving the image, 
the world is preserved.

A possible way is to do the morph deletion in a #whenUIinSafeState: 
block, or a lower priority forked process.

An alternative is to use app specific code to build your world, and 
install it. Any old world would be just forgotten. See implementors and 
senders of #recreateDefaultDesktop.

Cheers,
