- Start Dedicated Server (I have CBA enabled)
- Start Headless Client (Optional)
- Start 'Players' Client & connect to Dedicated Server
- Select mission 'COOP10 Escape from Stratis'
Play the mission as you want (I just used 1 player, disabled AI) and walked along the eastern side of the map, mostly.
Upon disconnection I checked the server RPT to find the errors I've mention within the Description above.
