well,i started heatran's quest i lost a couple times then i decided to start genesect's quest i just got 1000 hours,at the bug catch i noticed that i had lost 1 master ball and about 120 rare candys,without the masterball i coudnt catch genesect so he got killed.I wonder what happend i may have used the masterball before accidentally but im pretty sure i didnt use the 120 candys that i had,its common to vanish itens from the inventory or anythin like that? sry for my english.
