Since the beginning of [Arts and Crafts] update until now (update 193328) I cannot connect to my old existing worlds.
I also could not connect to other people' server,
Then, I tried to create a new world WITH cave and it's not working either. However I tried to generate a new world WITHOUT cave and it's working.
So, I think there is a problem with the server for cave.
BTW I am in Germany.
Generate or join worlds WITH cave cannot connect. Generate world WITHOUT cave still works.
