Rook's Weapon Appearance brok BD armour

I had the Blood Dragon Armour as pre-purchase items. Then I installed the Rook's Weapon Appearance DLC which was available free, and the BD items disappeared from my wardrobe, from the current playthrough and all the earlier ones. I removed the DLC, which didn't help, and made a ticket, got some copy-paste replies from EA Help that were no use at all, and then they outsourced the problem to the forums, telling me to seek a solution there. They've also force-closed the ticket without a clear option to keep it open. So good job there too.

My game is bought on Steam, which says EA doesn't manage their items there so contact EA Help. EA Help tried to tell me to contact Steam. VG doesn't show up in my EA App, perhaps because the game doesn't support linking between EA App and Steam (if it did, the Steam page would say so, right, like it does for DAI?), even though my accounts are linked.

I tried uninstalling and re-installing the game and verifying the files, but no effect. I used to have the items so no doubt EA could give them back to me if they could be bothered. Which they obviously aren't. Luckily, I wasn't expecting much from the ticket, and that's what I got. With all the issues other people are having with their items, it seems it's pretty much a matter of luck whether you actually have the items you've earned or paid for.

So, anyone here have a solution?
