I had both upgraded "Seeds of Doubt" card having loss the incept effect. I upgraded both to have the draw bonus effect "Visionary Doubt". At the end i only had the draw effect on both of them. I can't tell precisely when the bug occurred i think it's when the card is upgraded to this effect (draw). I had used "Boosted Doubt" working normaly. During this playthrough i also use the "consumable" card to increase xp gain on card.
Upgrade this card to have the +draw effect.
