After 2 hours offline and don't know if a other friend have come online in the 2 hours i got the message when try to join the server:

downloading map
loading multiplayer map
waiting for server to save map
Saving local variant
Redownloadingloading map
Creating desync report

You desynchronized from the game (have now the options:)
-Show desync report
-Quit game
-Reconnect

So i don't know what happends, but got a desync report.
And don't have contact with the friend that runs the server and the other player.
Post that when i got it
