So this was an issue when I first made the server until a buddy figured it out. I had turned off the mini map, left HUD on, turned on/off the various other HUD related options from above and the HUD stayed on constantly when testing. Then I went back into portal, turned on the hardcore toggle...saved...then turned off the hardcore toggle and saved again, and then the HUD started to disappear after inactivity. We believe that turning on the hardcore toggle setting enables some hidden settings that aren't available in the portal UI. The big thing is that after you enable hardcore toggle and then disable it, you have to go back because it'll change some of your settings back to their defaults. So try to remember what settings you've turned on and off, and then after you toggle hardcore, save, and then turn it off again and save, go back and re-enable or disable the settings you want and you should have it where your HUD will go away after an activity. Another thing is if your server is up and running, when you change any sale things, you have to take the server down and then re-host it in order for these settings to be applied. Let me know if that works for you as we can then confirm that this is the process to hide the HUD after inactivity.
