If you’ve crafted a higher Mk ship but aren’t seeing an upgrade, here’s how it works:

Crafting an Upgrade
When you craft an upgrade, you're not immediately upgrading the ship itself. Instead, you’re creating a single upgrade token for that specific ship, similar to the ones you can buy from the Black Market.

Applying the Upgrade Token
To apply the token, go to your Fleet Manager screen. Select the ship you'd like to upgrade, then apply the token. Once the upgrade is complete, the token will disappear.

Crafting More Tokens:
After using a token, you can continue to craft additional tokens in the Workshop to further upgrade your ships.

Good luck with your upgrades!
