Oh, I am sorry for that! I was so busy with other stuff and forgot to search for bugs like mine!
Is there really no solution?
Buying a new router doesn't work or anything?
I really want to host a server with my friends, but I can't get around this error. Where can I stay most updated about this bug, here?
I have the same issue and it does not appear to matter if I am near one of my villages or in a new quiet location I am working on. I get about 20 minutes in to a session, disconnect and lose progress.
Very frustrating having to chop down the same tree several times.
