I was configuring tweaks for my Angel/Bob/Clown pack, wanted to leave Bob's warfare productivity on, and for some reason couldn't get the setting to work. (The checkbox worked, but prod stayed disabled even if I unchecked the box.)
I dug into the mod and realized that you have "if settings.startup["remove-bob-warfare-productivity"] then" on prototypes/productivity-fixes; all the other settings checks have ".value" after the brackets. I patched that in and the prod setting works. Figured you may want to toss that in the next bugfix.
