Kaniks

hi, my nickname is Kaniks from gold server. I was battling with an NPC at Medusa's Cloud and then server crashed during the battle and now i can't go there because sailor Jenny doesn't show me the option. Before that i neutralized nidokings and nidoqueens of the Nido isle for then go to Medusa's cloud. I talk with Ayva but she doesn't answerme. I tried to restart the client, change map, battle with another NPC but nothing happens.
