3 bugs I have noticed in the current calculator build:
1) Sabitha is allowed to eat the demonic fruit ingame during chapter 5 cycle 2, after the 2nd gathering and before the incubus war. Currently the calculator does not allow that option until after the incubus war, chapter 5 cycle 3.
2) In the warden of the south section, the 'Find Ancient Books in Givini Tower and Watch the Ceremony' states that it increases Wendis cohesion by +2 (and the wiki agrees). However clicking that button mistakenly adds +3 to the cohesion value instead.
3) This one is harmless but for the warden of the south, clicking the recover the shining sword button adds +2 shining swords if the 'Find Ancient Books in Givini Tower and Watch the Ceremony' hasn't been clicked yet. Once both buttons are clicked, the shining swords added goes back to the correct +1. This bug doesn't really matter since the find ancient books button has to be clicked anyways to complete the warden of the south.
