After I've finished Dewford Gym, I went to the old man at port then told him to bring me to route 109.
I was farming Ev a few min and decided to go to SLATEPORT CITY.
After I enter SLATEPORT CITY, My character appeared a few seconds and changed to loading map and the connection lost in the end.
I tried to lock in again but my ID can't connect, just loading and disconnect again and again. (;w;)
