Hello,

I got this bug with my Seasonal Character + Playing with a XB controller (did not try to repro on my other characters). I might have been sleepy but when checking my inventory, I forgot I was in the shop menu. So instead of using them, I sold them by mistake. 

Worst, I notice this also locked the Tarot Seals of this season. As a fix, I sold all my Tarot Cards, played a mission to get "new fresh ones" and I was able to use them this time. 

I looks the issue is related to Tarot Cards you buy back from Van Wynter.
