Yes, I'm the creator of the game. I was troubleshooting while waiting for a reply. It was only affecting one character. I have "universal equation" fields players can enter data into that is meant to be added to every attack and damage roll. While more than one player had something in the universal damage field (the affected character had the Power Attack question, another question had a Hideous Blow question), only one was affected. I just modified the sheet to put parentheses around the calls to the universal question fields and it seems to have cleared up the issue. I still find it odd that it only affected one character even though the code was the practically the same.
