Excellent!  I can believe that changing the time zone specification
has helped as I know that I had real problems when I tried BST instead
of Europe/London.  However, why CEST should work when there are no
VALARM entries is a total mystery.  I do agree that it's likely that
Google's import facility is getting confused when the ICS files get
more complex...

Anyway, glad you have it working!
