I know about that, that's not what I'm talking about. what I'm talking about is this: I feed a unit several other units to raise the bond level, I save the game, I close the game, I reopen the game and load the save, and the bond level is reset to 1. I rarely if ever even enter combat mode. when looking at the save file with a text editor, there is a saved 'level' stat for the unit that is equal to what I got the bond level to, but again, when I load the save the bond level is reset to 1
this is before saving,
this is the save file after saving and closing the game,
and this is the same unit after loading the save file
