So I bought bounce from the fisherman at the Lake of Rage and it was taught to my Magikarp for 4,000 pokedollars. I get out of the area and then log out. I log in the next day and it's gone from the Magikarp moveset. So I buy it again. The same thing happens. I don't understand why this keeps happening but it's really getting annoying. I shouldn't have to buy it more than once for it to work correctly.
