I thought we were talking about a dragon that’s fully trained and levelled up, but the spirit doesn’t level just as much? This happens a lot.
Also, you are referring to a dragon that’s in need of training after levelling up their current star to maximum. How’s it possible to still keep levelling up a dragon we haven’t trained to next star? As far as I know, only thing to be done is wait and try to meet the requirements for the training session. Levelling up before training to next star doesn’t seem like an option. Believe me, I have tried.
Oh, ouch, how could this happen? Aren’t having the copy, along with the scales required, and the fish needed, a guarantee that the dragon will progress in training to next star?
