Re: DA:Ultimate - DLCs Present, but no Promotional Items
The free promotional items aren't included in DAO:UE, and have always had to be installed separately.
I know Origin downloads and installs them (and I believe the GOG version of the game does as well), but I'm not familiar with Steam's offering... though a quick glance at the product page for the game does not seem to mention the promotional DLCs being included.
So, first, I'd recommend confirming whether or not the promo item DLCs are installed > Click on 'Downloadable content' on the menu load screen:
That will open a list of all installed DAzip content (both Bioware and any community created mods). If the promo DLCs are installed, they'll be in that list:
If they aren't in the list, then the next step is to determine whether that is an issue with Steam, or not. And if Steam does not include the free promo items in their DAO:UE package, they can be downloaded and installed manually from Bioware's CDN, via the Dragon Age Wiki > Downloadable content (Origins)
