Whatever was done with the most recent patch on the Pathfinder sheet, it did not adequately address the problem of Buffs failing to modify attacks properly. Even after repeated use of the 'Recalculate' button, changes were sporadic when they happened at all. For instance, with a Buff that added 4 to Strength, out of 6 attempts it only modified the "to hit" field of Attacks once, and never modified the damage field at all. As stated, this was after using Recalculate both before and after switching the Buff on and off. If it is relevant, I was NOT using the 'bonus stacking and buffs' option in Setup.
