Forum:Save worked once , didnt work again

Alright, i was playing PTD like any human being, as i continue to the Celedon gym andbefore that i saved, worked perfectly. Then i met Celebei or something like that, i failed like twice, then i decided to go train my pokemon, but THEN when i went into my pokedex, it said i logged in somewhere else please log back in , and then BOOM im back in the cave with the big onix and all my pokemon are deleveled and i lost my shiny meowth that i got in Route 8. Is this normal for people or is this a glitch, im quite angry right now.
