Anyway, within a few seconds, the sparkles re-appear. If I try to collect again, I will get the 'Oh Darn!' sync message. I have simply learned not to collect unless there are other sparkles nearby. Now your syncing problems may result from something else altogether but perhaps this could be worth looking into.
I don't know whether deleting and downloading would solve the problem but it's not that serious for me now that I have isolated what triggers it.
