At the 22.12.17 I was playing on gen 3 with my friend. My friend went to gen 1 - server 7 for some reason and I wanted to join them. I couldn't join because it was loading the terrain for a very long time and then I disconnected. I retried some times it didnt work. At the next day this friend was still in gen 1 - server 7, I was able to join this time but the friend wasn't there but on the friendlist they were on server 7. It happened on server 7. Sorry for my grammar.
