Correct Heroes and @aliveserver should go into the root A3 server directory, not in a sub-folder
For War Room - make sure you've followed the server setup instructions after logging into WR. Test by:
In server.cfg include persistent=1;
Start your dedicated server with the following mod params -mod=@CBA_A3;@aliveserver;@ALiVE;
Start your Arma 3 client with the following mod params -mod=@CBA_A3;@ALiVE;
Main Menu > Multiplayer > select your dedicated server > JOIN
/ #login yourpassword
Maps > Stratis
Missions > ALIVE | Quick Start (COOP 9)
Select a slot (Squad Leader)
When the map loads, if you have successfully saved a mission before with SPOTREPS, PATROLREPS, SITREPS or markers, they should be displayed on the map. The map diary should also include entries relating to the reports.
A hint to the right hand side should appear stating your web profile has been loaded, if not persistence has failed.
If you have saved a previous mission, then you should be restored to your last location with your last loadout.
