I didn't play the game for a long time so Idk if these bugs fixed or not.
when the AI charge his KI and get for the first bar. he instantly try to transform. I think that the AI should decide when he transform and when not while having good amount of KI+ when AI transforms he never try to get to his base form.
everytime I shoot a little KI blast at the enemy and he get dammaged from it he instantly start charging his KI
