Same here. Happened to me after 27 character-days during which I've enter/exit the cave for many times. Then this one time when I enter the cave, the cave loaded but it looks like it has freezes and my character is missing. After a few second the disconnected message show up. The server is still up and server information show that I have a character on the server. Try to rejoin the server the game will either disconnects, or show the same freeze screen describe above before disconnecting. Update: I try again and this time the cave is actually raining so its not freezes. My char is still missing but I can see the shadow of his.
