A friend of mine created a "friends only" server that we played on for about 270 ingame days. For some reason, this server is now completely offline and we can't make it online again.
We tried 3 different rollbacks, cloud saving import, USB save import. It didn't work.
I've seen people complaining about servers becoming ONLINE, but not the other way.
He asked me to post this here because he struggles a lil bit with english. If you need, I have his Klei ID.
