Incomplete Synchronization

[jinydu]

Sometimes, after a server synchronization, I find that some of my completed exponents from the previous round remained in my cleared list on my individual account report. That is indeed what happened with today's synchronization, which left M17373287 in my account report, even though it had finished on March 6.

Why does this occur?

A server synchronisation does not remove all completed work. It removes it only up to the end of the previous month. On my stats page for instance I still see the following :

You can see that all completed work from 2007-03-01T00:00 onwards has not been removed.
