Lady Ravendancers tarot deck not working

Just discovered this today when the grandmother in my legacy save died and passed the tarot deck down as an heirloom.No options to use it appeared. I sent the sim that inherited the deck to read the tarot shrine, thinking that might make it acknowledge I had the complete deck, but it’s just gave me the first card and set off the quest chain to complete the deck. Essentially, once the sim that created the deck dies, that deck is worthless. Now I think this is terrible gameplay, because of course a spellcasting tarot reading medium would pass her tools down to the next interested younger relative, but I suspect this is working as they intended. If you want the fancy deck for a sim, you’ll have to work for it every time. I won’t be, because it takes too much time, so I’ll just use the basic one, or maybe I cheat myself enough aspiration points to buy the fancy one with. But it won’t be the deck the grandmother used, and it won’t be an heirloom, so it sorta ruined my story a bit. Pretty disappointing.
