I've noticed a bug in the pathfinder sheet where it does not correctly calculate some character's AC's. Right now I have a character with a Dex bonus of 4, a size penalty of 1, and no other bonuses that it is calculating as 18. I did at one point have bonuses that would have added up to 18, but at that point it was calculating it as 13. Any tips for getting it to properly calculate short of remaking the character?
