I almost succeeded with fixing it, but I'm still getting an error sometimes. I need more mitm logs to know exactly what I'm missing...

Are you required to send player location after defending pokemon faints?

[Gegy]

START_GYM_BATTLE is sent when a defending pokemon faints, and the player location is sent in that.
