I've encountered a small bug in 5.7.1. I have all of the weapon cards unlocked, but in the card display in the mini gallery, some of the special animated weapon cards are still blacked out.
If it's any help, the special cards that do show up in the mini-gallery are the ones that I unlocked before they became special cards. It might be the case that the mini gallery is checking for the wrong card variation (clothed/nude) since the special cards only have nude variants.
