With this update we are trying to address some of the matchmaking and disconnect issues which have been troubling to some. Internal testing show that things are more stable but as always the three of us cannot possibly recreate the experiences of all of you. So please keep the bug reports coming and a big thank you to everyone for helping us make co-op better!

Two issues remain but there is a workaround:

ISSUE 1 - no one can find your game session
If a game session is being hosted but no one can find it, then something have gone wrong between Unreal Engine and Steam. This problem is on the side of the person hosting the game session, and in order to fix the issue the host should follow these steps in order depending on HMD:

HTC VIVE and WMR

1. Shut down the game completely.
   
2. Shut down Steam completely. Cannot be running in the background.
   
3. Shut down Steam VR.
   
4. Restart Steam.
   
5. Start the game and try hosting a new game session.
   

OCULUS RIFT

1. Restart game.
   

ISSUE 2 - indefinitely spinning wheel
If searching for a game session to join or trying to host a game session results in an indefinitely spinning wheel with a text saying searching, then something have gone wrong between Unreal Engine and Steam. In order to fix the issue follow these steps in order depending on HMD:

HTC VIVE and WMR

1. Shut down the game completely.
   
2. Shut down Steam completely. Cannot be running in the background.
   
3. Shut down Steam VR.
   
4. Restart Steam.
   
5. Start the game and try hosting a new game session.
   

OCULUS RIFT

1. Restart game.
   

Sincere apologies for not having a fix yet for these hopefully last remaining issues but rest assured we continue working on them.
