Missing items from gold upgrade

If you very recently purchased the gold upgrade and the items are missing from your in-game inventory it probably means the game needs to be restarted. The gold items work differently because they pre-date the regular purchasable items and are actually sold as downloadable content (DLC). While the game is launching Steam checks for any DLC-related items and adds them to your inventory.

The same applies to gold benefits like character slots and customization: the game needs to be restarted because Unturned only checks for DLC ownership during startup.
