i have a theory on this, and its crazy, but i think it pinpoints the issue: 
  
many players aren't able to rejoin the server after a crash until there is a queue. if you try to join, you are disconnected right after the loading screen, as shown in the video posted above. but as soon as there is a queue, you are able to load into the game just fine, no disconnect. 
  
please can the staff look into this, this is madness. More people will quit playing when they grow frustrated from the instant disconnect, resulting in not enough players to create a queue. And no queue means that people with the instant disconnect issue will never be able to connect again. Your servers are basically unplayable (for a large amount of players) after a server crash, if there aren't enough people to cause a queue....
