The recalc option in my sheets is not working. I've noticed that some sheets actually did some calculations, but others did not. I believe that the old sheets are the ones with issues. For instance, this sheet bellow: The bonus field for buffs is showing Not a Number (NaN) and this sheet is older than the buff section. There are several wrong calcs, like the initiative bonus. If I create a generic buff, this issue is solved. Maybe some buff's attributes should be created automatically to solve this issue on old sheets. However, there is still some problems involving NPC HP and others.
