Hi everyone, the problem was I lost against Yellow in burned tower and he told me that: "I'm still looking for information around here..." and he block my way.

I have an screenshot!;

Thanks.

Little up, i got the same problem as him, i've lost against Yellow, did the quest to save the kimono girl and look at the gym.

 

But when i go to the gym, the guard told me the gym leader is in the burned tower but, i can't pass since i'm stuck against Yellow and i can't battle her again, every time i try, i got the same problem that Miller.

 

SO i hope someone will help us because we can't advance if it's stays like this :/
