Motorola Droid :: Inconsistent Results With Sync Of Recurring Events?

I have noticed for some time now that my Droid can sometimes lose some of the recurring events in my calendar. They "dissapear" even when I haven't made any changes to those events. (If it happened once, I would admit that I may have done something and forgotten. But, I've had the problem for a while and am very careful with recurring events because of it.) Toggling the sync in the Settings>Accounts and Sync section sometimes helps, but often the best workaround is to make some minimal change to the event by logging in to Google Calendar and resave it. I typically add a space to the end of the event name. Once I do this, the future events appear on my Droid once again. Because this workaround does the trick, I assume this is a bug and not user error.
