Actually hold on, are you referring to the digipedia descriptions? Those are the only areas where I feel the writing feels clunky, but those are directly taken from the digimon reference book. If those are what you mean it's not really the fault of the developer and they are quite literally translations from Japanese.
No not the Digipedia descriptions..Just as an update, I haven't noticed any mistakes since after the prologue. That AI lady had a few mistakes but I can't go back and give you examples without restarting the game..It's all really just water under the bridge because this game is super amazing! I wish official Digimon games were this good :3
