• Fixed Mutation menu background (Went black for some reason.)

• Updated the ugly "Add-on Campaign" icon.

• Fixed an issue with the order of campaigns being incorrect in the mission list.
  
• Included a missing texture image for add-ons without images (for my own sanity).

• Mutation menu updated to match the reset of them.
  
• Main menu add-on spinner has been restored.

I reinstated the accidentally removed Friends menu.

The add-on preview image has been adjusted to a square, rather than a rectangle.

A few menus, including the Add-on menu, have been updated to be more user-friendly.

Friends menu has been added back after feedback.

The "Steam Group Servers" button has been removed as it can be accessed in the "Campaign" menu and for a cleaner look.

• This has now been updated to include the Versus Survival mode.
  
• The Singleplayer menu has been moved into the Campaign menu as per the update.
  
• I have also removed the "Play" in each mode for a cleaner look.
