Issue Description:
Certain gamemodes or settings tweaks may case one or more parts of your on-screen heads up display to disappear.
Solution #1 - Use ChangeHUD Command:
Hiding parts of your HUD is actually a feature of Nerf ArenaBlast. Currently, the default key to cycle through HUD modes is F5. Press this repeatedly until the HUD looks the way you would like it to. You can also use the console command ChangeHUD if you are an advanced user or cannot remember your ChangeHUD keybind.
