I bought the deluxe eddition through epic games on day one

The reason I asked if you were launching it from the EGS is that if you launch it from the folder, the game cannot do the authentication check to see if you own the DLC, but it can if launched from the EGS. Something about how the DLC was included

Chitin Armor Set DLC for Backers?

It’s included as part of the game itself - it doesn’t appear as a separate item. But I did discover yesterday that it checks your Epic account for eligibility - so if you’re not running through the launcher, the DLC doesn’t show when you start a new game.
