With patch 1.2.2 the disconnecting problem was fixed for us. My brother and I could play without disconnects. We decided to start over again and played for two weeks without a single disconnect. Not one! We build a new base, did 2 labs, etc. Not a single disconnect. It was awesome, we had a great time and were looking forward to the rest of the game.
Then patch 1.2.3 came out. Believe it or not, after that patch the problem was back. Constant disconnecting! Not the host, but the player who joins. So we were hoping that patch 1.2.4 would fix it again, but unfortunately it didn't. It's unplayable again. Disconnects within the first minute of playing.
Just to make clear. We have no problems with disconnects playing other games. Other games work just fine. This is not a problem on our end, it's your game. There is something weird going on when people are playing within the same household. Again, a problem we do not have with other games. The super duper update somehow fixed this issue, but for some reason, the 2 latest patches have brought it back.
How long has this been going on now? Since launch. Heck, some people even encountered this during the early acces. And you guys still haven't fixed this? We can't play your game in coop, as intended! This is getting beyond frustrating...
