it would have to be right after the chandelure event, i was surfing around the cave because i was curious were it went. i was doing my best to avoid the trainers but i didn't dodge one and he had three pokemon if i remember correctly. his lead was a magneton, and that is when i realized 5 out of 6 of my pokemon were still fainted from that chandelure. From now on i will make sure i save or fulled healed before i explore
