Copied and fixed in a custom sheet, but I don't have a Github account to make changes to the public one (and am too lazy to make one). On the 'General' tab, Move and Lifting values weren't calculating properly. For Move, the value was 0, or negative if any positive modifier was added. Turns out the item name for basic_move_max was missing 'attr' in front, line 352. As to the lifting values, the calculation was wrong. It should have been (basic_lift) * X, but the sheet was actually calculating (basic_lift_max) + ((basic_lift_mod)*2). So, for instance, a modifier of 2 on BL of 20 gave Simple Lift 22, One-Handed Lift 24 and so on. A simple workaround I used at each instance was to substitute (basic_lift) for the two attributes it adds, looking like this -- round(@{basic_lift_max}+@{basic_lift_mod}) * 2) Not sure if these issues are known, but whatever, it worked for me.
