HANAKO-CHAN'S PROFILE

Hi, I've played this for some time and enjoyed it quite a bit. :D
However, I'm having problems with the game.
Reached the 3rd battle, but the game freezes during the battle, and after restarting a few times, even if I defeat the 2 sailors (without freezing), this error message appears when the trio starts running away:

Scrip 'Game_Character 2' line 186: NoMethodError occurred.
undefined method 'list' for nil:NilClass

Is there any solution to the problem? :x
