I recently unlocked Calliope. After cycling through all of her initial free cards, I noticed that I got a higher level Lute that was locked. So basically I didn’t have one that I could use yet. Weird that the character model still showed one though. Whatever. Maybe it’s just a mandatory prop for that character.
Ok, so the actually buggy part is when I go to BUY some common Lute cards from the store. After purchasing, I head back to Calliope’s inventory and notice that the Lute item is STILL grayed out. Can’t equip, can’t upgrade - even though I now have 20 cards worth of Lute. Also the bonus effect doesn’t show up in the little hex window.
I now have two Lutes that I cannot use.
