The issue with newline characters in the ICS file has been fixed (as mentioned in this weeks' changelog on beta).? As well as loading correctly in Outlook, it also now works when syncing to Google Calendar.
Mark believes the issue with 'all day' subgroup events appearing on the wrong (previous) day is time zone related and he will investigate further when he returns from holiday w/c 29-Apr.
