CONNECTION PROBLEMS

[TH00R]

I play this game with my girlfriend since early access. Since the early access, there are connection problems. The "not host" got kicked out every 30-50 minutes. Now, since the latest updates, where they "fixed" some multiplayer issues, we have to restart the complete game every 5-10 minutes, because the "not host" and sometimes even the host, have "connection problems". Even though, we are playing with 1Gbit Lan connection. How can we fix this? Is there a possibility to play offline with a friend over LAN and not over the broken XBOX network?
