Started playing on 1.6.8. There's a bug where whenever I save the game, party members' HP decreases.
I have a party of Knight, Fighter, Witch, the Oracle, and Wizard. I go to the heal point and heal everyone to full, then I go to the Unconscious and save the game. As soon as I leave the Unconscious and go back into the field, instead of being at full HP, the Knight's HP has dropped to 25/47, the Fighter's to 27/42, and the Wizard's to 20/21, while the other two stay at full HP. This was already happening for a while before I realised it was saving the game causing it, and it's easily reproduce-able because it happens every time, with the same values. Formation doesn't affect who loses the HP; it's always those three specifically.
