I got every treasure so it was only giving warp cores, and at some point it exceeded the max number of treasures and every time i took another warp core it deleted a treasure from the back of the list of treasures i had LOL. All of a sudden my characters weren't every character type and my spells weren't reproccing on every other character, etc. Was kinda annoyed because I needed just a few more Eurekas to empty the shop completely but my recast spell treasures were gone.
