I defeated Mole Marc while doing the Volcanion quest, and after I beat him he was talking to me (hadn't given me the red stone yet) and I got a phone call and looked away from the game and i got kicked for being afk. When I logged back in I was no longer speaking to Mole Marc and he would just say "have fun on your adventure!" or something when I would talk to him and the red stone still wasn't in my inventory. I gathered the other two items and Dr. Reinfield won't let me progress the story because I don't have the red stone. What do I do? I can't rebattle Mole Marc. Please help.
