I am still on TB 115.18 with CB 94.5. In later CB versions birthday synchronisation with the calendar unfortunately does not work properly any more.

I am using the birthday field in CB and would like to have the dates shown in a separate birthdays.ics calendar, which is included as follows:
file:///d:/mozilla/thunderbird/profiles/user/calendar-data/birthdays.ics
In CB settings, the birthday calendar is selected.

As soon as the first birthday event is in the past, calendar.ics gets write protected, the calendar selection in CB breaks and a synchronisation is no longer possible.

Only when selecting calendar offline support, the error does not come back. But then the calendar is no longer selected in CB settings.

CB is a very useful TB Extension, but with this bug I can only rate it with 2 stars.

How can I get this to work again?
