You may either want to post the mission here, or post your server rpt from the session you saved and the session you loaded. Database persistence is pretty reliable these days so I'm going to guess the solution here is simple (i.e. Mod conflict, or module not set properly or server info not setup correctly on the site, etc).

It's possible you're thinking your mission is saving because your profile is updating on War Room. These are not the same thing (though I can see how someone would assume one connecting would mean the other was working, etc).
