• Fixed Slap causing aim to be reset on every instance
• Added css_restart to restart the game (css_restartgame, css_rr, css_rg)

Config updates:

• Added DefaultMaps and WorkshopMaps to add maps available in the menu (as we can’t get full list automatically yet)

Please note:

• I do not add 'rare' commands such as ban from ID, unban... etc
• It will require some new localisation keys
• Menus should be respecting the immunity and flags, but I did not test all possibilities
