Tried a whole bunch of different types of recurrence series - with 
exceptions, without exceptions, daily, weekly etc... Tried deleting 
various instances as well as "all future" instances. Nothing I do 
shows me this behavior.

The loadEventsCallback() method is called after the server response in 
is received on line 4335. I guess you can start there...

Still not seeing this.

I created a new recurring event that recurs daily, every 2 days for 10 
recurrences.  I then deleted the 5th recurrence. The events disappear 
briefly - really just blink - before the series is added to the view 
again.

Tried deleting a number of other events from this series, all with the 
same results.

The cache is updated correctly, just not the UI.
The example I tries was a daily recurrence every two days for a 
certain number of instances. Then delete single instances while in the 
dynamic month view. All recurrences disappear and only reappear if I 
switch views.

The series is removed, but then should be re-added from the data 
returned in the deleteEvent response from the server. Just tested this 
and this is exactly what happens for me locally.

After deleting single (or all future) recurrences of an event, all 
recurrences are removed from the current view.
