When you have multiple people at the same location and you encounter a Warrior of Wrath in "Into the Runeforge," the primary character will get a proper acrobatics roll. But subsequent rolls will roll off screen and result in an automatic zero.

I am having issues with just one character.  I am not allowed to play any cards and if I click on another hero to use cards, my die disappears.  I cannot proceed.

Thanks for the additional information with the 0 result dice issue. This will help!
