I want to make the Vortex Bulwark. I have the 6 different ingredients. However of my 5 "Hard to Kill" cards, I have 2 listed with an (F) after it. This prevents the card from stacking to 5. It stacks to "3 Hard to Kill" or "2 Hard to Kill (F)". Since the Nexus only holds 6 ingredients, I can not use two slots for the two supposively different types. PLease fix this. You should be able for example to transform any card to remove the (F)...
 "Cardinal Chains"){kind=icon}
 "Clash of the Dragons"){kind=icon}
