Look in the stats, where are you missing one?
Viewing post in The Dollsville Upgrade (V10.0.2): The End of Dollsville comments
Open the command panel (maj + O, esc to quit it) and enter the command:
str(paladin_level) + " " + str(prystal_level) + " " + str(gwyn_level) + " " + str(kassandra_level) + " " + str(voxlyn_level) + " " + str(jessie_level) + " " + str(felicity_level) + " " + str(azula_level) + " " + str(singer_level) + " " + str(real_jessie_level)
Then hit return/enter, it should print the level of the entities, which should be
3 3 4 3 3 5 4 4 2 3
If it isn't, it will show you which one isn't maxxed out :)
