I’m all out of ideas, sometimes it works and sometimes it does not. The level inconsistency is so high I’m about to lose my mind. We’ve tried using VPN, we’ve spent some hours making sure everyone’s router settings are set up properly*(ports 27000-27050 and 7777,7778)*. We’ve tried DMZ mode on all ends. Nothing.
I’ve compared logs over and over, no errors, just warnings from unrelated games such as Stellaris and Hearts of Iron 4. It might be the region lock, it may not. I’ve tried it with 2 people with varying results, one from Norway and one from the UK*(I live in Sweden)*. I really can’t put my finger on what it may be, but my assumption is Steam’s test app ID just an utter mess.
If you ever get the time, would you mind taking a look at my project? It’s not too big at the moment as we haven’t started adding assets yet - it’s ~99.5MB when compressed in a .rar archive. I’d greatly appreciate it.
