Sometimes when I connect to a game I download a small map and start to catch up. During the "catch up" phase I get a message that the server is pausing to save. The catchup fails, It proceeds to download a map that is 3 times as big or MORE and then immediately desyncs. This has happened twice now and I don't know what's going on. All vanilla.

What you are downloading after it fails is already the reference part of the desync report. NaB.

The desync may be a bug, though - are you using any mods or server scripts?
